Browser window bound to Slack snap


I have a weird problem with the slack snap and it only happens under specific condition.

If I open a link inside slack with Firefox, the Firefox window gets bound to the slack icon. So if I minimize the slack window or end it, my Firefox window will get minimized or closed as well, but only if I haven’t open any other Firefox windows before.

But should I have already open a Firefox window separate this does not happen.

I checked if the same is happening with the snap discord and there it functions normally, it opens a separate Firefox window

Anyone knows a fix?

snapd version 2.30
snap slack 3.0.5
