Unexpected mouse focus during export

[AUD 3.4.2 on Win10]
I recently had to export a large numer of tracks, one by one. CTRL+SHIFT+E brought up the export dialog OK, and after I had set the inital preferences, I could continue without mouse hitting ENTER to start the export for each track. Once the export was finished however a dialog pops up informing me of the path and filename exported. This dialog has a blue frame around the OK button, suggesting you can quit this dialog also with ENTER. No luck, however: the cursor (and focus) sits in the path/filename and I had to use the mouse to click OK.
Why is the focus in a field where there is nothing to edit?
And why is a button marked as “focused” it it doesn’t have the focus?
So I would think this is a bug. Albeit minor, a fix would help productivity a lot if you’re about to export some 20 or more tracks …
