Where the font came from, and when

Site: https://github.com/googlefonts/noto-fonts/blob/c8729a9e61b2a54a9d2b4c61a82d4d93213bd6e3/unhinted/otf/NotoSansJavanese/NotoSansJavanese-Regular.otf Date: 2022-04-20

Font version

Version 2.002

Issue

Below-base combining characters should be positioned relative to, and may ligate with, pasangan forms, but this font ignores any intervening non-spacing pasangan forms when shaping below-base combining characters.

This is an anchor attachment problem (and the one I warned @marekjez86 about). The situation is that when he builds the font, the signs attach (incorrectly) to the bases, and when I build the font, the signs (correctly) attach to the subscripts. One day (soon) GitHub Actions will be building the font, and we will both have an independent build to point to which does not depend on our specific environment.
