Leaving a room while one of its widgets has set setAlwaysOnScreen(true) makes the widget linger invisibly

[squahtx]

Steps to reproduce

Reproducible with the FOSDEM 2022 talk widgets.

1. Join a FOSDEM 2022 talk room, eg. #talk-13559:fosdem.org
2. Join the Jitsi call in the widget. This calls widgetApi.setAlwaysOnScreen(true).
3. Switch to another room. The Jitsi widget now appears in a small picture-in-picture overlay.
4. Leave the talk room. The picture-in-picture overlay disappears, but the Jitsi call in the widget is still running.
5. Visiting the room under the Historical section shows the Jitsi widget still running.

Outcome

What did you expect?

Either the picture-in-picture overlay should remain after leaving the room, or the widget should be destroyed.

What happened instead?

The widget remained running in the background.

@vector-im/product which of these is preferable?

[jakewb-b]

I would say the widget should be destroyed if you've left the room.

[t3chguy]

@jakewb-b what about if you're looking at the room when you leave it, you'd probably also want to leave the call?

[jakewb-b]

@t3chguy - yes, that's what I'd expect
