The HarfBuzz rendering of Arabic is the correct one in this screenshot.
For debugging the such rendering differences, the actual font used by
Emacs for a given part of the text need to be known, then the text and
the font can be checked against vanilla HarfBuzz (e.g. using the hb-view
command line tool); if it gives the same rendering then it is either a
HarfBuzz or font issue, if not then it is a bug in the HarfBuzz
integration code in Emacs.
