I'm a bit confused as your comment both says 98b8 is affected and that you can't repro on beta - which versions of the flatpak build of Firefox are affected? I would expect it to be all of them...

Hello! I'm sorry for the confusion! This issue is not reproducible on a normal, non-flatpak beta build. I tested it in order to confirm if this is a permission-related situation or if it's an issue. This issue only reproduces with flatpak.
