Sorry that I come that late to you; I have been offline for a couple of days.

I could reproduce it also on Emacs 24.5.

Anyway, I've started yesterday working on this. Not trivial to fix, I
fear. As consequence, any fix will go into the master branch (Emacs 26)
only.

There is also the bug report #24889 about this. Further communication
shall happen there.
