Yes, that's true.

Is the input focus there, or does the input you type arrive at that
frame (instead of the minibuffer frame)?  As we established, the frame
that has focus and the frame that gets the input can be different
frames, thanks to redirect-frame-focus.

I see in the code that read-from-minibuffer (or, rather, one of its
subroutines) does the equivalent of the following:

   (if minibuffer-auto-raise
       (raise-frame minibuffer-frame))
   ...
   (or (eq (selected-frame) minibuffer-frame)
       (redirect-frame-focus minibuffer-frame))

Does your setup have minibuffer-auto-raise set to a non-nil value?  If
not, can you see if setting it non-nil fixes the problem?  (I'm not
saying that this should be the fix, I'm just trying to figure out
which part(s) of read-from-minibuffer fail to do their job.)
