Upgrade MathJax to v3

[hno2]

Hey,

upgrading to v3 of MathJax would/seems to improve performance quite a bit.
I tried out changing the hardcoded URL in math.py and it seems to work, but I have no special settings set.
That is the problem I currently see as the settings in MathJax 3 are handled differently than in v2.

Thanks for your work!

Hi @hno2. Is this issue something you would be willing to help out with? We could really use the assistance! 😅

Hey @justinmayer . I will have a look soonish. Though I have no experience with MathJax Settings, but I'll see what I can do.

@hno2: That would be great. Looking forward to it! 😁

Hey @justinmayer, so I had a look at the settings of MathJax3 (vs MathJax v2.x). And there are some breaking changes, so I want to check in with you first to get your opinion. Implementing the MathJax3 is likely to break a couple of settings. So I am waiting for your feedback before going back to implementing them.

• latex_preview is not implemented in MathJax3
• MathJax_font Currently only the TeX font is available (HTML-CSS.availableFonts not implemented)
• linebreaks are not implemented in v3 currently. The whole topic responsiveness seems to be (still) an issue
• messageStyle is not available in MathJax3

Disregarding these issues, the change to MathJax v3 seems like a very good idea performance wise.

Hi Simon. Please accept my sincere apologies for the absurdly-long delay in responding to your detailed assessment of the potential breaking changes in MathJax v3+. Do you know whether any of the potential breaking changes have been addressed in the intervening years? 😅
