Can't re-mount removable media that the desktop previously automounted
OS: Fedora; Component: gparted.x86_64 0.33.0-1.fc29 @updates
Tested on Gnome on Xorg; Gparted won't be launched on variations Gnome or Gnome Classic. It may be an issue. An external storage device is involved in the present case. While the USB-labelled device is mounted, invoke Unmount option.
Attempt to mount back the partition to its existing mount point by invoking Mount option. That last cannot be selected since it is not activated.
