1733087 - Don't unload tabs that are playing audible audio content

Status: RESOLVED DUPLICATE of bug 1733002

(Firefox :: Tabbed Browser, defect)

Description

[Paul Adenot (:padenot)]

Similarly to 1733002, tabs that are playing audible audio content cannot be discarded, and there must be a fairly long (low two digits number of seconds) before considering the tab as unloadable.

It's fairly common for websites to implement playing an album as having one <audio> per track, and starting playing from the "ended" handler of the previous <audio>.

Additionally, this need to function on an audibility basis (which is computed in Gecko already, and readily available for all audio-producing objects), not based on the playback state.

This wasn't the case on Android twice (in the Fennec days, and then after for Fenix, I had to fix it twice), and each time there were lots of users annoyed by this behaviour.

[Tracking Requested - why for this release]:
Per :padenot, this has been an issue in the past. Unloading audio tabs might be a problem on release that we have to issue a dot release fix for.

The patch of bug 1733002 covers this scenario.
