Minimise to tray not working on Wayland, since Wayland has no concept of "iconised" windows (Upstream issue bug 1872790, unfixable?)

[Alex9001]

When using Wayland on Plasma 6 Betterbird does not have a tray icon showing and does not minimize to tray. I have minimize to tray enabled.

Works as it should in X11.

OS: Artix Linux

If I see it correctly, Wayland isn't fully supported by the Mozilla platform, see all the "Depends on" in this meta bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=635134

That the window doesn't minimise is due to the fact that internally a "sizemodechange" is not received. We debugged this with another BB user, who in the end reported this upstream bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=1872790

You can repeat the steps in the description of this bug, that is, paste
top.window.addEventListener("sizemodechange", () => console.log("sizemodechange received"))
into the error console and see what gets logged when minimising the window.

You will find that nothing gets logged, hence the app doesn't receive the signal that it was minimised, so it can't minimise itself to the tray. Sorry, blame it on the Mozilla platform.

I'm reopening this, so it's easier to find.

Please note all the fine debugging we've done on the issue, see: #377 (comment).

TL;DR: Wayland doesn't report windows being minimised or iconised.

No problems when restoring the window to "normal" (not maximised) size? See discussion at #377 (comment).

I was on 115.18 before, which worked just fine

No, it didn't, see long discussion in Issue #377. Turned out that 115 never ran under Wayland (#377 (comment) and above).

Build updated:

We're not going to post further updates, just use the latest "latest".

Let's close this now. We can open a new ticked for the graphic anomalies. I've asked @mfschumann whether he can reproduce this in his FlatPak build.
