Sometimes firejail -noprofile --appimage $Appimage leaves AppImage mounted even after closing/killing/terminating it

[neurodiverseEsoteric]

Specifically, it's been an annoyance with Biscuit, where I'll find several copies of it still mounted with no means of getting rid of them other than restarting the PC...The mount point also appears to move from /run/firejail/appimage to /run/media/${USER}/path (or something like that...I don't have time to reproduce the issue to check if "path" is the correct mount name...I'm just writing this so I don't forget for the googleth time)...Is there any way besides rebooting/logging out/etc to get rid of these vestigial AppImage mount directories?
