Thanks, I think this is a much better variant.

Are you sure posn-window cannot return a frame?  For example, on a
TTY, I get this:

  (posn-at-x-y 0 0 (selected-frame))
   => (#<frame F1 069b0190> nil (0 . 0) 0)

And (0,0) are coordinates in the frame's menu bar.

Does it make sense to install this patch on its own?  If so, we can
install it without waiting for the legal paperwork, the changes are
small enough.
