HTML-File to reproduce the bug

Overflow-Scrolling in context of details-element stopped working in iOS 10.

This is reproducible with the attached file in Chrome and Safari on iOS 10.

Steps to Reproduce:
1. The dom consists of the html-element <details>
2. Add other elements inside <details> that are longer than the details-item itself so it overflows and is scrollable. The content must contain interactive elements.
3. Add an event listener for a touch event on that page

Expected Results:
The list should be scrollable.

Actual Results:
On iOS 10 the list is only scrollable outside of the link-area (on list-item-points).
