Unfullscreening videos in Firefox moves Firefox to the wrong monitor
Fedora 31, gnome-shell 3.34
I have no clue whether it is gnome-shell/mutter or a Firefox bug. If you think it is a Firefox bug, we can move it over there.
When you unfullscreen a video in Firefox and Firefox was moved on another monitor while the fullscreen video was running, Firefox is returned to its initial monitor and not the one on which the video was running in the end.
Steps to reproduce:
- Have two monitors connected
- Open Firefox on the primary monitor
- Open YouTube in it and start a video of your choice
- Fullscreen the video
- Move Firefox onto the second monitor
- Unfullscreen the video by pressing Esc
Actual behavior:
--> Firefox is moved to the the initial monitor
Expected behavior:
--> Firefox stays on the monitor on which the video was running in the end
