Hi folks,

Starting emacs (https://emacsformacosx.com/) from a macOS terminal prompt
causes a warning which suggests something may break in the future:

<-->
% emacs -Q
2022-01-23 14:30:34.131 Emacs-x86_64-10_14[32403:2930258] It's not legal
to call -layoutSubtreeIfNeeded on a view which is already being laid
out.  If you are implementing the view's -layout method, you can call
-[super layout] instead. Break on void _NSDetectedLayoutRecursion(void)
to debug.  This will be logged only once.  This may break in the future.
<-->

There are no apparent ill effects apart from the irritating terminal
noise. The same warning appears if the program is launched using

<-->
% open /Applications/Emacs.app/Contents/MacOS/Emacs-x86_64-10_14
<—>

which creates both an editor gui window and a separate terminal
window containing the warning text.

The full stacktrace is:
