Sorry, this bug was introduced by my commit
4915ca5dd4245a909c046e6691e8d4a1919890c8.  I canceled it in commit
6b2c8dc9050c5c0514fa404733ce1d4a37d00e39 due to a performance issue,
but the cancellation was incomplete.  Attached is the patch to fix
this in master with an ERT.  Is it better to fix in emacs-29?
