Sorina, the test seems to have been done with 68 nightly but 67 is marked as affected as well, is it? Thanks

Pascal: Hi! Yes, this is also reproducible on Firefox 67.

I tested this on Samsung Galaxy Note 8 (Android 9) and I found a regression for this issue:

playbackState's default value is PlaybackState.STOPPED.
We can only enter PiP mode if media is playing but we don't save this playing
If the user hasn't done anything to change this, like pause-play, when we check
the playbackState in BrowserApp to know to force fullscreen if still playing
we will not do so because the state is PlaybackState.STOPPED.

I tested this on the latest version of Nightly 68.0a1 (2019-04-20) with OnePlus 5T(Android 9), Samsung Galaxy S8 (Android 9) and I wasn't able to reproduce the issue.

Due to my findings, I'll mark this issue as verified on Firefox 68.

Thank you.


I performed the test case posted in Comment 0 on a Pixel 3 XL (Android 9).
On Beta 67.0b13 video controls are displayed when returning from PIP.

Due to my findings, I'll mark this issue as verified in Firefox 67.
