Comment (by ballapete):

 It plays no role in which variant of GNU Emacs I perform this simple test
 (`X client`, NS variant `Emacs.app`, Mac variant `EmacsMac.app`, or
 without own windows `in Terminal`), or which version (27.x, 28.x, 29.x) I
 use – the result is always the same. And it also "works" on `High Sierra`.
