In some very specific cases changing the tab with the keyboard doesn't work.

Steps to reproduce

1. Open at least two databases
2. (Close and reopen KeePassXC - I'm not sure if this is needed)
3. Unlock one database
4. Press Ctrl-Tab or Ctrl-Shift-Tab

Expected behaviour

KeePassXC should navigate to the next or previous tab.

Actual behaviour

Nothing happens.

Workaround

Doing any of the following seems to "unstick" navigation:

• Lock the databases using Ctrl-l.
• Click on an entry in the now open database.
• Click on another tab.

Context

These keyboard shortcuts are really useful.
