I think one of possible solutions could be painting to 2 different graphic 
I.e. paint the whole ligature to one GC while lam is clipped out, and 
paint the whole ligature again to another GC with alif being clipped out.
Of course, to simulate a single lam-alif, accurate measurements to 
properly set positions/clipping would be needed.

" I can see why an expectation that color (or underlining) should not

For generalized font and style breaks, I think it would be enough to 
recommend that these are not intended to break shaping runs.
How would you handle the lam-alif ligature, if it had a font or style 
break between the two letters?"

I will add that even a color change, which appears to us as reasonable and 
useful, is not so easy to realize when done between  lam and alif.
