@waksmonskiMT : Sue, I verified it with my recent build that it is happening. Could you check if you build exhibits the same properties? I'm trying to see if this is a font issue, pipeline or harfbuzz...

This is still happening in both sans and serif. In the Sans, some of the issues are mitigated by using alternate forms of the vowel signs: but these alternate forms are not present in the Serif and will need drawing.

For the ja+medials I have no idea what they are actually supposed to do in that case. The longnow Bali fonts (https://github.com/longnow/bali-fonts) have the same problem. I think we need to find someone who knows what those combinations should look like.

Ja Jera (U+1B1B) is not really used anymore in modern orthography. and it's the rarest letter to appear in a sentence, if so, it most likely without any medials. But, if you want to handle/accomodate such combination, we can shorthen the Ja Jera and pair it with a short version of nania (medial Ya).

Here's how it is handled in Javanese.

example of Ja Jera usage:

I think if this is not happening in any attested words, and the Longnow fonts have the same problem, I'm going to say it's a non-problem until proved otherwise.
