Video rotates from landscape to portrait Firefox Android

[caeci11ius]

This was working really nicely on the Android version of Firefox until about a week ago. Since then, it's been causing the video player to rotate back to portrait periodically during playback (sometimes seems associated with skips, but not always). Happens within a few minutes regardless.

Phone is configured with automatic rotation disabled. Commencing in portrait, Firefox will rotate to landscape when fullscreen playback is selected. After a few minutes of playback with sponsorblock running, the video will rotate back to portrait. Skipping forward/back using double tap restores landscape orientation, as does exiting and re-entering fullscreen. Disabling plugin fixes the issue.

Plugin version 5.5.9
Firefox version 124.1.0
Pixel 7 Pro 5 March 2024 firmware

+1 came to report the exact same behaviour, as well as doing so randomly and during skips, seems to sometimes react to touch input to the screen
