If we're already on the destination frame, then I'd argue that if that
frame is not visible it's a pre-existing condition and there's no
particular reason to "fix" it at that time.

IOW I think that in window--maybe-raise-frame

              ;; Assume the selected frame is already visible enough.
              (eq frame (selected-frame))

should apply not just to raise-frame but also to make-frame-visible.
