I've found the reason, please see the attached patch. If it works for
you, I'll put in master.

With your latest diff, and nothing additional on top of it, and with

(defun tty-3 ()
  (interactive)
  (setq tty-3
	(make-frame
	 `((parent-frame . ,tty-2)
	   (left . (- 10)) (top . 5)
                   ^^^^^^^

the placement of tty-3 seems wrong. Just saying, I think you mentioned
that you fixed that already.
