Thanks, but I toured the whole settings yesterday, together with Gnome Tweaks, Dconf and the dock-to-dash settings and didn't find anything. Granted, I don't have a great handle of Dconf, so there are things I didn't touch to avoid messing everything else up.
This seems to be exclusive to Bazzite Gnome. I've used Gnome with absolutely every distro and this has never happened before. It's not a bug, it's a feature I don't like, lol.
I guess I'll take my chances on breaking it all and roll back if needed.
