'last-focus-update' could be used to put focus back to the same frame
where it was before saving the desktop.

Maybe then the desktop should save the selectedness as well.
I see some ‘(selected . t)’ in the desktop, but it seems
these indicate the selected buffer, not frame.

In your case above, if you save the frames is such order that
the selected frame is not saved last, can you reproduce the problem?
I see this problem often when the last frame is not selected.
