Khmer(km) font (and other scripts with ascenders + descenders) render badly broken in Firefox

See original GitHub issue

Observed behavior

Screenshot from 2020-12-14 21-36-58

Khmer language rendering is not correct in latest Firefox on Ubuntu gnu/Linux. Somehow Google-chrome handles this much better.

Developer tools console in FF reports(Not sure if this related):

[WARN: kolibri/core/assets/src/utils/setupAndLoadFonts.js] Could not load full font for ‘km’ setupAndLoadFonts.js:78:14 In Firefox, Noto Khmer font seems to be sanitized. downloadable font: rejected by sanitizer (font-family: “noto-full” style:normal weight:400 stretch:100 src index:0) source: http://127.0.0.1:8009/static/assets/fonts/noto-full.NotoSansKhmer.400.woff

Expected behavior

This is how the font is rendered in latest Google-Chrome. Screenshot from 2020-12-14 21-51-04

User-facing consequences

@radinamatic I have tested 0.14.6alpha release on my development machine. It does fix the font issue for Khmer and Hindi.

Once the PPA repo packages are created for this release, I push build so our team could do further testing.
