Description Petr Kočandrle 2019-10-03 11:07:09 UTC
Description of problem:
When I switch away from Firefox to another app by Alt+Tab and then I want to scroll a displayed page without switching back, just hover on Firefox window, it does not scroll but goes in page history back and forth as if I was still holding Alt key. 

Version-Release number of selected component (if applicable):
firefox.x86_64                       69.0.1-3.fc31

How reproducible:
100%

Steps to Reproduce:
1. Start Firefox while another non-fullscreen app running
2. Create some browsing history
3. Switch to the other window using Alt+Tab keys
4. Hover on Firefox window without switching there and use mouse wheel to scroll

Actual results:
Firefox going in browsing history back and forth

Expected results:
The page should scroll without any url changes

Additional info:
Running a wayland session, I haven't observed such behaviour in any other app (e.g. Chromium works fine), so I expect it is a Firefox problem.
