We are sorry for not having been able to help for long time. Recently we
began to think that this bug is the same as bug#33139, though it is not
yet confirmed:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=33139

We finally managed to fix that bug, so we hope that this bug is fixed as
well. Could you try the latest development version in the git repository
or the ELPA release which is to appear soon?

Regards,
Ikumi Keita
