With what font? AFAICT it should work, but some fonts "helpfully" render <shadda, fatha> and <fatha, shadda> so that they look the same regardless of the order.

With Noto at least.  Maybe that font has those tables too.  I wonder if CGJ should get some special treatment when it comes to jumping over Default_Ignorables?

Ok this is a Noto font bug.  Reported here:
