Hi Alan,

I applied the patch and rebuilt Emacs, then ran

    (let ((frame (selected-frame)))
      (make-frame-command)
      (set-frame-parameter nil 'parent-frame frame))

And the subrole of the new frame is now “AXFloatingWindow”.

I think that will do it. It there anything else that I can do?

Sincerely, Yuan.
