Hello, Platon.

Thanks for taking the trouble to report this bug, and sorry for the
annoyance it must have caused.

Indeed, yes.  Thanks for doing the bisection, it saved me a lot of work.

I've committed a fix for the bug to the master branch of the repository.
Would you please update your copy of Emacs, test the fix, then either
confirm the fix is complete, or say what is still not working.  Then we
can close the bug.

Happy New Year!
