Steps to reproduce the problem:
Requires: touchscreen and touchpad (eg, Microsoft Surface Pro 3)
1. Open website in a tab
2. Scroll with two fingers on touchpad
3. Scroll with touch flicks on screen
4. Scroll with two fingers on touchpad: FAIL (in just this tab, or other tabs where touch has been used)

What is the expected behavior?
Continue to scroll as normal using touchpad after using touch on-screen

What went wrong?
2 finger touchpad scroll no longer works after using touchscreen to scroll.

Did this work before? Yes Unsure - its not a common use case so I don't recall when it worked last, but I know it did
