It's not foolproof, since display-buffer can reuse an existing window,
or pop up a new frame, or (with the appropriate user customizations)
something else entirely.  I think it's reasonable to expect that if
the user clicks somewhere, he or she does not expect the window
configuration to abruptly change "under the mouse pointer".
