Details

This is pretty much similar to bug 1787079, but on Mac. Without the changes for bug 1787079 I attached in that bug, you can see the broken state on Windows as well, but the changes fix this issue on Windows at least.

STR;

  1. Open the Mac's display settings and choose a scaled larger text resolution
  2. Open https://media.prod.mdn.mozit.cloud/samples/domref/fullscreen.html
  3. Play the video in the content
  4. Press Enter key to make the content fullscreen
  5. Choose the display settings window by pressing Command+Tab
  6. Choose a smaller text resolution

Actual result; the video doesn't get fullscreen-ed.

This is not a recent regression, I can see the issue on Firefox 91.
