The font is fine with other
OpenType engines as well, e.g. HarfBuzz, so it is probably a ConTeXt

Yes, the font is fine with OpenOffice, too.
It would be really great, if this could be fixed in context, so one
could typeset quran (and other traditional arabic) professionally. Would
be very valuable!
I uploaded a beta that might fix it, but it needs more testing. The
issue might have been introduced when support was added for more complex
ligature building, compare for instance this:
\starttext
\def\sample{نَسْتَعِينُ وَلَا الضَّالِّينَ}
\def\sample{نَسْتَعِينُ}
\def\sample{\Uchar"0643\Uchar"0644\Uchar"0651\Uchar"0627\Uchar"064E}
\setvariables
[otftracker]
[font=file:uthmantn1ver10.ttf,
size=24pt,
features=arabic,
direction=-1,
title=Feature Check,
sample=\sample]
\page
\setvariables
[otftracker]
[font=file:arabtype,
size=24pt,
features=arabic,
direction=-1,
title=Feature Check,
sample=\sample]
\stoptext
(So Kai needs to run some of his tests.)

ps. some of the somewhat complex implementation will be redone when we
have a pending extension to glyph nodes in the engine done.
