1979737 - YouTube video stops playing after navigating to Tabs Tray

Status: NEW

(Firefox for Android :: Tabs, defect)

Description

[Nicholas Poon (redirect NI to [e-mail]) [:Nick]]

Steps to reproduce

1. Play any YouTube video in fenix
2. Click on the tabs tray icon

Expected behavior

Video continues playing

Actual behavior

Video pauses

Any additional information?

This is likely due to the Tabs Tray change from a bottom sheet to a full screen fragment. Testing on similar scenarios, navigating to the HomeFragment or SettingsFragment also pauses the video. Opening the menu redesign (another bottom sheet) does not pause the video.

This is likely a youtube issue that is only reproducible on Fx143, since daily motion is working fine. Testing on similar scenarios, navigating to the HomeFragment or SettingsFragment have the same behaviour as navigating to the Tabs Tray, which means that it's likely not an issue with the Tabs Tray change from a bottom sheet to a full screen fragment.

On Fx141 and Fx142, daily motion is working fine. However, on youtube, the video continues playing as expected after navigating to the Tabs Tray, but only because the Tabs Tray is still a dialog on beta and release channels. After navigating home on youtube, the video will pause

On Chrome, the actual behavior is occurring (video pauses after navigating to tabs tray)

Tom is working on investigating this issue as it is likely a WebCompat issue and not a Tab Management redesign issue as I previously thought.

I tried running a mozregression and this isn't working as expected from Fx135 up until Fx143 (didn't test any further beyond v135 as I believe it's a WebCompat issue)
