More information was requested, but none was given within 2 years.  The
last person to write in the thread cannot reproduce this bug.

I'm therefore going to assume that this has been fixed, and close this
bug report.  If this is still an issue in Emacs 26 or later, please
reopen the bug.

Best regards,
Stefan Kangas
