bug#60740: 29.0.60; Broken isearch-emoji-by-name

I couldn't reproduce this with the above command (and also tried a
few other emoji commands).  But I haven't tried with the version of
transient in emacs.git, and I have somewhat recently fixed related
issues in transient's own repository.

Recently I also noticed that my most recent attempt to update transient
in emacs.git has gone wrong; I think I just forgot to push.  I intend
to merge transient.git into emacs.git very soon (it's all bugfixes and
minor cosmetics), but have come aware of additional problems that I was
planning to address first.

When will that be?  I also want to get the latest bugfixes in before
then and maybe even create a transient release before that happens,
but I would also like to avoid rushing it, if I can help it.  (That
being said, fixing these issues is my top priority now, so I hope to
be ready to merge very soon.)
