SUMMARY
Mounted LUKS encrypted device cannot be reopened in Dolphin from the "Disks & Devices" applet.
The entry cannot be expanded, thus actions for Opening in Dolphin, etc. are not accessible.
The only available action is to Unmount the device.

STEPS TO REPRODUCE
1. Attach LUKS encrypted device.
2. Open it (from the applet or with Dolphin).
3. Provide a valid password.
4. Check the "Disks & Devices" applet's entry for that device.

OBSERVED RESULT
The entry cannot be expanded, and therefore actions for opening the device in Dolphin are not accessible.

EXPECTED RESULT
The entry should become expandable, showing more available actions.
