I can't reproduce this on current master, and neither could two separate
reviewers in 2015 and 2016. I'm therefore going to assume that this has
been fixed and close this bug report.
If you're still seeing this on the latest version of Emacs, please
reopen the bug report.
Best regards,
Stefan Kangas
