Web-app on iOS8 doesn't transfer Touch events to iFrames - javascript

In a web-app, on iOS 8.1, touch events (touchstart, touchend, etc.) don't seems to be transferred to iFrames, but on the same device in Safari they are.
I tested the same web-app on iOS 7 and again, the touch events are transferred to the iFrame perfectly. So basically, the problem seems to be directly related to iOS 8.
Unfortunately, I didn't found any documentation on the subject.
Anyone have encounter the same problem, found a workaround or know if there is an official bug report?
Thanks

Javascript Touch Force on iPhone

I have implemented reading the touch force for haptic touchscreen as per https://developer.mozilla.org/en-US/docs/Web/API/Touch/force
If I test in chrome debug tools on a PC (set to mobile) then it will register the force as 1 (as far as I can tell there's no way to simulate a different pressure). So I know the code it correct.
However on my iPhone XR which does have a haptic screen it always registers as 0.
The compatibility table says Safari on iOS support it, and I haven't been able to find anything that says you need to request the user permission for the feature (like you would with device orientation).
Any ideas why it isn't working?
on caniuse you have more details on support for iOs Safari, please check your safari iOs version is >= 14.5.

Scrolling differences on Safari and Chrome (iOS) can you test for them?

It used to be (before iOS 8) that Safari couldn't natively animate on scroll, you had to stop scrolling to see the animations. Safari solved that issue, but when accessing the same website on Chrome (running in iOS) the issue persists. I read that chrome hasn't yet updated this on iOS. I know that it works great on Android... so... Is there a way to test for this "feature" either with modernizr or other js? I would like to disable animations on scroll if they are not supported. I've been able to accomplish this by checking which browser the user is using, but it would be easier if I could just check whether the functionality is available.
Before iOS 8, iOS would pause painting while the user was scrolling. This behavior was discontinued for applications using WKWebView but remains for browsers using UIWebView — this is why you only see the old behavior for certain third-party applications.
One approach is to detect whether your page is loaded inside WKWebView or not. An answer to another question suggests testing for indexedDB support. indexedDB is the only HTML5 feature difference between the WKWebView and UIWebView.
The snippet from the other answer suggests how to do this:
if (navigator.platform.substr(0,2) === 'iP'){
//iOS (iPhone, iPod or iPad)
if (window.indexedDB) {
//WKWebView
}
}

Angular application doesn't work on iPhone/Safari 5.1.7

Currently am developing a big project in AngularJS(version 1.3X), Bootstrap(3.3.1), animate.css and few other libraries.
I do test my application on different devices via Google Chrome Developers mode and on few browsers like Google Chrome, Mozilla Firefox and Safari(for Windows7).
I also have possibility to perform tests on Android device and iPhone.
For some strange reason my application seems to work on every device except for iPhone 5 with Safari 5.1.7(when using same Safari but on Windows7 it does work).
Has anyone before stumbled uppon similar problem?
#EDIT
Sorry, forgot to mention what is actually happening.
When I try to press button that's supposed to toggle (using jQuery, I know it should be done via ui-routing, but that's how my boss wants it) portion of the view (panel) it does not work. Buttons do not perform any actions. There is no reaction.

Touch events are not firing on inputs iOS8 standalone web app

In a standalone web-app launched from homescreen, on iOS 8.1(8.0),
touch events (touchstart, touchmove, touchend) are not firing on inputs/textareas, but on the same device in Safari they are.
I've tested the same web-app on iOS 6 and everything works as expected.
Has anyone encountered the same problem and found workaround for this issue?
Maybe there is official bug report? Unfortunately, I've found nothing on this subject.
Seems that touchevents in a standalone web-apps launched from homescreeen are back with iOS 8.1.3

Touch events available in Safari?

A friend and I were discussing Mozilla's latest touch support and got on the question of what Safari provides for this. Searches seem to turn up nothing.
Do you know of anything that provides touch events to Safari on desktop, either via multitouch trackpad or direct screen interaction (I guess a Windows multitouch environment would be the only relevant case here.)?
No, there is currently no support for touch events in the desktop version of Safari.
According to this documentation it is only supported on iOS 2.0 or later.
