Hmm... yup.
I pushed to Emacs a fix for the generation of that Texinfo element in
`ox-texinfo.el` and to `m-buffer` I pushed another change which tries to
workaround that bug (for when it's used with an older Emacs).

The patch for `ox-texinfo.el` is below.  It's "obviously safe", but
I suspect it's too late for Emacs-30.  Eli?
