Noto Sans Balinese doesn't provide required ligatures for suku, suku ilut

What steps will reproduce the problem?
1. Use a current version of Firefox or Chrome.
2. Go to http://lindenbergsoftware.com/google/noto/bali-suku.html
3. Compare the rendering of the combinations of the dependent vowels suku and 
suku ilut with various Balinese conjunct consonants in Noto Sans Balinese with 
a reference rendering and the rendering in Aksara Bali.

What is the expected output? What do you see instead?
Suku and suku ilut should form ligatures with the conjunct consonants in which 
they change their shapes to something similar to the Western digits 2 and 3, 
and in several cases move to the right of the conjunct rather than below it. 
This behavior is documented in The Balinese Alphabet 
(http://babadbali.com/aksarabali/alphabet.htm) and largely implemented in the 
Aksara Bali font. The actual behavior in Noto Sans Balinese is that suku and 
suku ilut do not change shape and are always rendered below the conjunct (see 
screen shot).

What version of the product are you using? On what operating system?
Noto Sans Balinese 1.02
Firefox 37.0.2 and Chrome 42.0.2311.135
OS X 10.10.3
