emacs -Q

Resize the frame using the mouse, so that the menu bar extends (is
wrapped) to be 3 lines.

(frame-height) ; ==> call it N

(set-frame-height nil (1+ N))

The frame height is *reduced* by one, not increased by one.

If the menu bar is wrapped to only 2 lines then the bug does not occur.

It does not matter what value option `frame-resize-pixelwise' has.
(And it should not matter - frame resizing should work regardless of its
value, with the only difference being the granularity - not the
direction - of resizing).
