Expected Behavior

My computer should shut down when I tell it to / KeePassXC should handle shutdown signals in the right way.

Current Behavior

Attempt to shutdown the computer graphically fails when KeePassXC is running and a database has been opened but is not visible. (Will KeePassXC prevent shutdown in other situations? I don't know; more testing is needed - but see this closed bug report: #2692.)

Possible Solution

Steps to Reproduce

1. Install KeePassXC snap on Mint Cinnamon 19.1 x64.
2. Open a KeePassXC database.
3. Minimise KeePassXC to the tray/panel.
4. Try to shutdown the computer via some (any) GUI. (Using the terminal may work properly.)

Context

It makes KeePassXC unworkable, forcing me back to KeePass-under-mono. Using the latter is involved, a bit slow, poorly themed and works badly with clipboard managers. Moreover, the whole point of KeeePassXC is to avoid such kludges on Linux.
