[legacy-v2/woff] LatinModern NonUnicode causes CSS height problem in Microsoft Word in Firefox

Created by: tomty89

Issue Summary

Having LatinModernMathJax_NonUnicode-Regular.woff in system causes lines in document opened in Editing mode in Microsoft Word (the online web app) in Firefox to have huge CSS (line-)heights. The problem is not observed in Chromium, so I cannot rule out that it is due to a flaw/bug in Firefox. However, other woff fonts in MathJax2 do not seem to cause the problem. Neither do I know whether Chromium cares about woff in system at all.

With the Arch Linux package mathjax2 remain installed, once /usr/share/fonts/mathjax2/HTML-CSS/Latin-Modern/woff/LatinModernMathJax_NonUnicode-Regular.woff is removed, the problem is gone.

Also see Steps to Reproduce.

Steps to Reproduce:

(0. Remove the mathjax2 package / fonts installed with pacman -R mathjax2)

1. Place mathjax2/HTML-CSS/Latin-Modern/woff/LatinModernMathJax_NonUnicode-Regular.woff under /usr/share/fonts/
2. Start Firefox and open any document with Microsoft Word (online web app); better use private browsing as cache seems to hide the problem sometimes

Technical details:

• MathJax Version: 2.7.9
• Client OS: Arch Linux
• Browser: Firefox 98.0
