[Bug]: Cannot open window if "Launch minimized"

[aleasto]

What happened?

Since upgrading to version 6.0.0 (rev 814) I have been unable to launch the Mattermost window from the tray icon.

If I rm -rf ~/snap/mattermost-desktop/current/.config/Mattermost/ to delete my settings then the window launches correctly.

Enabling File > Settings > Show icon in the notification area and Launch minimized and restarting the application the bug presents again.

Likewise, enabling File > Settings > Leave app running in notification area when application window is closed doesn't actually let me re-open the Mattermost window from the system tray.

This happens both with --ozone-platform=wayland and --ozone-platform=x11.

I don't see any relevant log so this may well be an upstream bug.

What should have happened?

Clicking on the Mattermost icon in the system tray, then $server_name, should open a Mattermost window to chat in the chosen server.

Likewise, clicking on the Mattermost icon in the system tray, then Settings..., should open a Mattermost window for settings.

This sounds like it could be an upstream issue - there have been a couple of similar ones in the 6.0.0 release.

Are you able to reproduce with the upstream deb? If so, could you file an upstream issue and post the link back to it here? (https://github.com/mattermost/desktop/issues)
