bug#65217: 29.1; set-frame-size gets confused and drops calls

[Ash]

From emacs -Q:

(setq my/frame
(make-frame `((left . 500)
(top . 5)
(parent-frame . ,(selected-frame)))))

(defun my/twiddle (width height)
(set-frame-size my/frame 10 10)
(set-frame-size my/frame width height)
(message (format "%s %s" (frame-width my/frame) (frame-height my/frame))))

Then call (my/twiddle 20 20). It prints "20 20", but the actual frame
size is 10x10. However, if you recreate the frame and then call
(my/twiddle 40 40) (or any size other than 20x20), the size is set 
correctly.

I'm running under Wayland using sway.
