Ok, so I pulled down our RedHat Indic test cases and they appear to be
the same before and after for this, so it doesn't obviously break
anything.

It seems more of a band-aid than a full fix to me, but it does improve
the attached to fdo#31016 test case. So I've pushed this now and added a
little one-liner define around the relevant bit to make it easy to
disable if any problems do arise.

So thanks for this, CTL rendering is rather tricky, and while there's
been a fair amount of work on Indic languages, Arabic is probably the
one in worst shape.

Can we take it that your submission is under our recommended LGPLv3+/MPL
licence ?

As an aside I'll try and see if we can free-up our RH Indic internal
rendering tests and submit them to libreoffice for regression testing.
