I also confirm this.  KMM 5.1.0, Artix Linux, KDE Frameworks 5.77.0, Qt 
5.15.2, KDE Plasma 5.20.4.

If I select a transaction, then switching desktops away and back changes 
focus to the last transaction on the ledger.  If I edit the transaction 
(ledger lens) then switch away and back, the same transaction is still 
open for editing.  However, on cancelling the edit, focus immediately 
switches to the last transaction instead of staying on the edited 
transaction.  As Thomas said, switching views within KMM also resets the 
focus, but that seems expected.

It seems not to be specific to one WM/DE, so I don't have any good idea 
how to troubleshoot further.
