Doesn't seem to happen with -Q for me, neither on master not emacs-30 (a
version of emacs-30 that is ca 180 commits behind; savannah seems to be
down again. This is macOS 15.5 on an M1 mac.

C-x 5 2 does not open a new frame on a new desktop for me. The new frame
opens on top of the fullsize first frame.
