Interesting, I found the solution. Hope it helps others.

It seems that it would be better to update the website configuration to switch to the CommonHTML or SVG output instead of HTML-CSS output to fix this issue globally?

Here is the solution to update the js to the CommonHTML or SVG output.

A general idea to fix this issue is to introduce a HtmlConfig field named mathjax_config to support setting different configuration files used by MathJax, and set the default value of this field to TeX-AMS-MML_HTMLorMML to be consistent with the previous releases. WDYT?
