File master key dialog loses password box focus on window focus (regression)

Hello, before 2026.2 I was able to use my password manager to fill the "File master key" in the dialog.
this is no longer possible with 2026.2.13.0 since the quick loss of window focus completely removes the focus of the control (password box) and pasting the password is impossible until you manually select the box with the mouse.

This used to work not long ago.
