to be clear https://www.gnu.org/software/emacs/download.html does
point to https://emacsformacosx.com/ which would indicate it's
official in some manner. even the `brew install --cask emacs` (which
the download page instructs) points to these builds. i didn't realize
it's not considered an offical build.

ok, i just built it from source (haven't done that in years, not as
painful as it once was), but still the same issue.

ok, i'm not sure how else to replicate it then.

yes.

i would think that any unbound key combinations should be passed to
the operating system, and with the *unofficial* railwaycat build, it
works.
