<pre>On Safari 10, by defining a simple listener that prevents default a 'touchmove' event within a scrollable element, the event is not prevent defaulted as it does with Safari 9.
The behavior between Safari 9 and Safari 10 diverges. It seems to be a regression.
This is reproducible here: <a href="http://codepen.io/anon/pen/PGRxOv">http://codepen.io/anon/pen/PGRxOv</a>
Probably a webkit issue.
Steps to Reproduce:
1. Take an element with scrollable content (overflow: scroll).
2. Add an event listener on it for "touchmouve" event, and call `event.preventDefault()` in that event listener.
Expected Results:
The element should not be scrollable. To try to scroll on the related element should do nothing at all.
Actual Results:
The element is still scrollable on Safari 10.
Version:
iOS 10.0.2</pre>
