Steps to reproduce:

2. In Windows snap the Firefox window to the left half of the screen. Other halves or quadrants should be able to reproduce the issue as well.

These fullscreen video player issues do not occur if the fullscreen video is launched from a non-snapped or fullscreen Firefox window.


Actual results:

The video appears behind the Windows taskbar and there are gaps beside the video on the left and right sides.


Expected results:

The video should appear in front of the Windows taskbar and taking up the full screen as normal.
