This still is an issue, also on Wayland and pgtk.  The commit
f208d5ae77 that introduced the problem is long but since
--without-harfbuzz does not change anything, much of the commit diff
can be ignored, I suspect.

@Po Lu: Since you seem to be into the low-level display code
currently, I shamelessly Cc’ed you.  Of course, this is not a
demand but possibly you have an idea.

Regards,
Torsten.
