Build ID: 20171009192146

Steps to reproduce:

I am on a Dell XPS 9360 with touchscreen on Ubuntu 17.04
Run firefox with the environment variable MOZ_USE_XINPUT2=1 i.e.
env MOZ_USE_XINPUT2=1 firefox
Right click anything by performing a long press on the touchscreen, then close the context menu.


Actual results:

Attempting to scroll by swiping now results in zooming in and out. This problem persists across multiple tabs, but not multiple windows. 


Expected results:

Swiping should result in scrolling normally.

Feels like a widget layer thing that we're not processing a "touchup" or something. mystor, can you reproduce on your xps 13 (maye different because this is Ubuntu and you're running Fedora)?

I can reproduce this on my laptop. The long press causes the selection to pop up, and the context menu shows up. I tap somewhere outside of the menu and now scrolling both scrolls and zooms in an unpredictable manner.
