"We need to get together with CSSWG/Houdini TF/etc to work out solutions that help those developers who actually solve the problem of math on the web." Unfortunately, Houdini seems to have deprioritized font metrics info currently so this might not come soon. See this issue for more details: https://github.com/w3c/css-houdini-drafts/issues/135 https://github.com/w3c/css-houdini-drafts/issues/135 (However, for math we often use webfonts anyway so it is practical to send down glyph metrics with the fonts. That's what both MathJax and KaTeX do.)
