1318462 - Play button shown on web.telegram.org even when there's no media to play and when the tab is in the foreground

Status: RESOLVED DUPLICATE of bug 1320005

(Core :: Audio/Video: Playback, defect)

Description

Attachment: Screenshot 1

On https://web.telegram.org, the play button is shown in the tab strip even when there's no media to play and the tab is in the foreground.

This isn't reproducible if you open a new window and navigate to https://web.telegram.org in the only available tab.
If you open a new tab, instead, it is reproducible.

I've noticed this regression recently in Nightly, but I'm not sure when it was introduced.

Play tab button is also shown when opening "Get Firefox for Android" thumbnail from the New tab.

STR:
1. Launch Firefox with a new profile
2. Open a new tab
3. Click on the "Get Firefox for Android" thumbnail.

Expected results:
The Play tab button should not be displayed in the opened tab.

Actual results:
Tab play button is displayed, even if there's no media to play and the tab is not in the foreground.

Alastor, are you going to be able to work on this regression?
