I have now committed the patch from Wednesday (slightly amended) to the
emacs-28 branch at savannah.  This should have fixed the bug.

Christian, if downloading the latest version from the savannah server is
inconvenient, please let me know, and I will send you the patch by email
so that you can patch your own version of Emacs 28.
