Steps to reproduce:

  1. Navigate to https://www.youtube.com/watch?v=E31fNqvEWTk
  2. Click "full screen" button in Firefox window (green window decoration)
  3. Play video
  4. Click PiP button overlay in Firefox

What happens:

The PiP window opens in a new fullscreen window and doesn't act like a PiP window (doesn't overlay other windows if moved to a different screen, for example).

Expected result:

As prior to regression.

I tested this on macOS 10.15.7 (19H1922) - I have not tried other macOS versions, so the behavior may be different elsewhere.

Attaching a recording of behaviour that I believe to be linked to this issue. This was tested on MacOS 11.6 with a 2 screen setup, with the source video open in a fullscreen window (via green button). (Video was also cropped to reduce file size)

Is backing out the regressor an option for release?

Is backing out the regressor an option for release?

This seems like an option to me, but the best person to answer this question would be the author of bug 1700674, Kris.

Flags: needinfo?(spohl.mozilla.bugs)

The bug is marked as tracked for firefox103 (release). However, the bug still isn't assigned.

:gcp, could you please find an assignee for this tracked bug? Given that it is a regression and we know the cause, we could also simply backout the regressor. If you disagree with the tracking decision, please talk with the release managers.

Based on prior discussion it looks like the best fix until we know what's going on here is to back out bug 1700674.

Flags: needinfo?(kwright)

Adding leave-open since this backout doesn't address the underlying issue caused in bug 1700674.
