- "sans-serif" was restored in 1.23 with https://gerrit.wikimedia.org/r/#/c/127132/1/ (340c01ed172c4257ce1f8d4fdb98802c6060bbac)
- No such removal for 1.24? Release notes have a brief mention with link to https://www.mediawiki.org/wiki/Typography_refresh in the "new features" section, but no notice of breaking changes and regressions especially for certain locales.
