Status: NEW

(Toolkit :: Picture-in-Picture, defect, P3)

Description

[Daniel Bodea [:danibodea]]

Found in

• Nightly v116.0a1

Affected versions

• Nightly v116.0a1

Affected platforms

• Windows10
• macOS 11
• Ubuntu 21.04

Steps to reproduce

1. Open https://www.hulu.com/ and open PiP for a random video. (US VPN may be necessary)
2. Modify the volume slider position in PiP and check the one in the original player.

Expected result

• The volume slider position of PiP is in sync with the original player's volume slider.

Actual result

• THe volume slider position change is NOT reflected in the original player.

Regression range

• Not a regression, but an implementation flaw.

Additional notes

• The actual sound volume modifications work as expected.
• Mutting/unmuting does not cause a similar issue, as they are in sync.
• This issue only occurs when modifying in PiP and checking in the original player, but not the other way around.

:danibodea, if you think that's a regression, could you try to find a regression range using for example mozregression?
