bug: statusTap issue with native scroll on iOS

[andreialecu]

Type: bug

Platform: ios 8 webview

When tapping the status bar in the new ionic master while there is a momentum scroll happening the scroll to top doesn't complete properly. It snaps to top then back down to where the initial momentum scroll's end position was. This happens with native scrolling.

This can probably be fixed by forcing overflow: hidden on the overflow-scroll="true" div to freeze the scroll.

This was also an issue in previous ionic versions with native scrolling on iOS.

@mlynch I opened a PR at #4748 which fixes this.

Thanks for guiding this one, I did a slightly different solution. Mind testing on WKWebView and letting me know how it goes?

@mlynch I just tested it and it works, however, I think .freeze should still be implemented instead of it being NOOP, otherwise when you start dragging up/down from the left margin so that the content scrolls, and then you drag to the right to enable the swipe to go back gesture, you can both scroll the view and expose the previous view which seems glitchy.
