User blog:Cloudy176/Math tags: follow-up

Here's a blog post about something I found four months ago but didn't bother to make a blog post about it until today. This is a follow-up to my previous blog post about  tags no longer working.

While I was patrolling Battle for Dream Island Wiki as usual, I looked at [?oldid=809972 this page], and it contains an expression that uses the  tag, and it was rendered using MathJax. This means that MathJax is now built into FANDOM wikis, and is now being used to render formulas inside  tags. My previous blog post was wrong;  tags do work on other wikis.

Then why didn't it work on here? When I went to a page that uses  and looked at the developer console, I saw an error like this:

Uncaught TypeError: Cannot read property 'a11y' of undefined at TeX-AMS-MML_HTMLorMML.js:65 at TeX-AMS-MML_HTMLorMML.js:65

Looks like the MathJax we installed on this wiki clashes with the now built-in MathJax, and that causes formulas in  tags to not be rendered. Now how do we solve this problem? We could remove our MathJax installation and change all formulas between  tags to   tag expressions, but I don't think that's the solution because that's not the only way we are using MathJax here. There are expressions that use the  delimiters, which causes them to be shown on their own line, centered. There's also some more exotic delimiters that are used to create long tables of expressions, such as the one used in the fast-growing hierarchy article.

So, what should we do about it?
