Demonstration of the bug

position: sticky will make an element "fly away" when scrolling if it is inside a fixed container that is inside a UIWebView.

This causes inconsistent rendering on iOS, as a sticky header in a sidebar will work perfectly when viewed raw through Safari, but fall apart when added to the home screen or compiled in PhoneGap, as those seem to use UIWebView.

Example attached as html file.

To see the odd behavior, add it to the home screen on any iOS device.

Tested on iPhone 5C iOS 10.3.2, iPad Pro 10.3.2.
