Investigate MathJax 4.0

[dae]

Mathjax 4.0 has been released, and this means the possibility of replacing computer modern. Is on the table? I am not sure how much is required for a switcharoo, or what is required for testing. Can I get a confirmation that this will likely be an addition? Or are there no current plans to incorporate it into Anki

Need to look into what's required for upgrading, try it out, and any explore regressions in a beta testing period.
