Template Literal Function not working as expected

I have a function that turns an array into modal window links as a template literal.
The code that creates the links works fine outside of the function
But once it gets rendered in the function it no longer works. I can't find any errors, but it does NOT work.
However, if I copy the HTML that the function renders and save that as actual HTML, that works fine on its own.
A good chunk of the JavaScript portion of the code is posted below. A full version is on Codepen.
There are two sections in the example on Codepen:
The first section has the code as it's rendered by the function.
The second section is copied from the Elements tab in Developer Tools and saved as actual HTML.

My apologies in advance for it not being stripped down to just the bare minimum. But in order to replicate the problem, it required more code than it probably should have had. I've been reworking this for the better part of a day without any insight as to what the real problem is. I've been creating functions using template literals just like this for years now, usually with a high success rate. Whatever the problem is, I need to know so I can get past it. The only anomaly that I spotted is that–in the version on Codepen–the only thing that doesn't work in that version is once the modal is displayed clicking on the background does not dismiss the modal like it does elsewhere. If that's significant as to what the problem may be, I'm not sure what the connection is.
Usually when I take the time to painstakingly write everything out like this I typically either spot the problem or figure out an alternative solution so there's no need to actually post a question, but this does not appear to be one of those times. As always, your help is very much appreciated!

The issue appears to just be timing. Your code is executed in order, and the first part gets all of the modal buttons on the page and sets the appropriate event listeners. Then the second part of your code adds 2 modal buttons, which were not present earlier.
By simply wrapping the first part of your code in a function and calling it later (or swapping the order of those two parts of code), everything works as expected.

Modal stops working after image changes on page

Im building an app where you can like and dislike movies. I have a database of movies and show each one to the user. When you click like or dislike it takes you to the next poster.
I also have access to the description and rating. I've added my own modal to show the user when clicked more information on that movie.
The problem Im having is the modal works for the first movie and changes the class to active. However on the second one it stops working. I can see in the inspector the modal code is there and has the correct information for that movie. But the modal seems to still not work/become unresponsive. Perhaps its an error that I've missed. I notice that it does add active once again on the first item. Perhaps I need to find a way to switch to the current movie instead or incorporate the modal into the slides more? or find a way to reset it..
EDIT -:
Adding to the above. Having done a bit more testing. It seems like the modal doesnt know what id the slide is on.. So it never knows when the slide is changed.. Any ideas how I would do this?
EDIT2 -:
I've now got it so every modal has a unique id per poster using the contact.id. Any way to link the modal id together with the slides so when I change the slide the modal knows and changes to active on the next slide?

This shows when the first poster is clicked the modal works and movie-modal active is added to the modal class
The second image with Morbius in it.. The modal class doesnt change for the current slide showing however it changes for the previous slide.. BUT the previous slide only changes once and then sticks to active. Nothing is shown on the poster.

Question on element alignment and how cursor is able to stay flush with the text in this editable code textarea?

Looking at this codepen, most of it I grok. But a couple of things I don't understand:
How does the <code> element stay perfectly on top of the <textarea>? I would expect it to be below the textarea looking at the HTML code.
How is the cursor staying so well-aligned with the text such that it functions like the type of cursor in a word document? The cursor even aligns well with the text when I copy and paste the text. Is it the emmet dependency that's helping?
Here is the code:

How does code and textarea elements stay aligned?
They are aligned because in the CSS they both use the same style which outlines the positioning of both elements. They both use position: absolute and the same top and left properties so stay in the same position.
See here https://www.w3schools.com/css/css_positioning.asp
In terms of the z-axis you can see that code has a z-index of 1 while textarea has 2 so text area stays on top.
How is the cursor staying aligned with the text?
There is no javascript acting on the cursor here. If you were to have any textarea in html the cursor would align with the text.

Hiding an element in internet explorer leaves artifacts on the screen (IE 10-11)

We use custom selectbox elements for our page (for reasons), but in one specific place and only with IE (in my case version 10 and 11), there is a problem.
When you open the box and close it, sometimes the browser leaves visual artifacts of that element. If there is a button below the element (in the opened state), then those artifacts are still on top of that button UNTIL you hover over the button, then those artifacts disappear at that place.
I think everyone experienced this behaviour at some point in his life with windows or something else. Sorry if my description isn't perfect.
Here are some screenshots (The red boxes are censored text, sorry):
Open state:
Closed state with artifacts:
Hope my description is accurate, I desperately need a fix for this.
I can't reproduce it on my system, but our QA guy can reproduce it consistently. It also changes depending on the size of the browser. On some sizes it doesn't seem to happen at all. It must be some weird rendering glitch of IE.
I don't think it has anything to do with our custom selectbox element, because it happens only in this specific place and in our old design we experienced it in a different place with a completely different element. At that time I thought it's because the DOM is too complicated for IE, but this page has almost no elements.
EDIT: I Just found out that if I minimize the window and maximize it again, the artifacts disappear, which should confirm that this is a rendering glitch, right?
EDIT 2: Here is the code and css of our custom selectbox
HTML:
<div class="input_selectbox">
<label>Title</label>
<div class="input_selectbox__head" data-placeholder="">
<label>
<input type="hidden" name="id" value="5-10909">
Dummy 1
</label>
</div>
<div class="input_selectbox__body">
<label data-value="" class="">

News/Image Slider for PHP Loop, (JS) Reset Interval on Click & Better Format for Unique ID's

I'm currently setting up a news/image slider on my site via JS. I have the slide data rolling in through a PHP loop with unique ID's. Everything is working smoothly, I just can't figure out how to reset the timer/interval when you manually switch slides.
Also, there has to be a better/easier way to write the manual click navigation I currently have setup with all the unique ID's. I have the loop sliced at 5.
(my code is a mess)
$(document).ready(function(){
$("#newsFeatured article:first").addClass("active");
$("#newsFeatured li:first").addClass("active");
});
var toggleSlide = function(){
$("#newsFeatured article.active").removeClass("active")
.next().add("#newsFeatured article:first").last().addClass("active");
$("#newsFeatured li.active").removeClass("active")
.next().add("#newsFeatured li:first").last().addClass("active");
}
setInterval(toggleSlide, 8000);
$(document).ready(function(){
$("#control1").on('click', function() {
$("#slide1").addClass("active");
$("#slide2, #slide3, #slide4, #slide5").removeClass("active");
$("#control1").addClass("active");
$("#control2, #control3, #control4, #control5").removeClass("active");
clearInterval(toggleSlide);
});
$("#control2").on('click', function() {
$("#slide2").addClass("active");
$("#slide1, #slide3, #slide4, #slide5").removeClass("active");
$("#control2").addClass("active");
$("#control1, #control3, #control4, #control5").removeClass("active");
});
$("#control3").on('click', function() {
$("#slide3").addClass("active");
$("#slide1, #slide2, #slide4, #slide5").removeClass("active");
$("#control3").addClass("active");
$("#control1, #control2, #control4, #control5").removeClass("active");
});
$("#control4").on('click', function() {
$("#slide4").addClass("active");
$("#slide1, #slide2, #slide3, #slide5").removeClass("active");
$("#control4").addClass("active");
$("#control1, #control2, #control3, #control5").removeClass("active");
});
$("#control5").on('click', function() {
$("#slide5").addClass("active");
$("#slide1, #slide2, #slide3, #slide4").removeClass("active");
$("#control5").addClass("active");
$("#control1, #control2, #control3, #control4").removeClass("active");
});
});

Lastly, i'm interested in getting my slide to interact with touch for mobile devices, if anyone can point me in the direction of a good tutorial on getting that started.
Thanks!

Clearing intervals is fairly simple:
function myFn() {console.log('idle');}
var myTimer = setInterval(myFn, 4000);
// Then, later at some future time,
// to restart a new 4 second interval starting at this exact moment in time
clearInterval(myTimer);
myTimer = setInterval(myFn, 4000);
Please check the snippet:
$(function() {
$("#newsFeatured article:first").addClass("active");
$("#newsFeatured li:first").addClass("active");
var sliderInterval = setInterval(toggleSlide, 8000);
$('.featuredControls').on('click', 'li', function() {
var $this = $(this),
id = $this.attr('id'),
index = id.replace('control', '');
slideTo(index);
// Clear interval.
clearInterval(sliderInterval);
sliderInterval = setInterval(toggleSlide, 8000);
});
function slideTo(index) {
var id = '#control' + index,
$this = $(id);
// Highlight active slide.
$(".featuredSlide").removeClass("active");
$("#slide" + index).addClass("active");
// Highlight active control.
$this.parent().find('li').removeClass("active");
$this.addClass("active");
}
function toggleSlide() {
// Get current slide.
var id,
index,
$next = $(".featuredControls .active").next();
// If last item, start over.
if ($next.length === 0) {
$next = $(".featuredControls li").first();
}
id = $next.attr('id'),
index = id.replace('control', '');
slideTo(index);
};
});
