It's been a couple years since PPCG voted against MathJax. Since then, the vote ratio has changed significantly, and most seem to be in favor of MathJax. However, it is status-completed and no change will be enacted on the current votes.
The issue then was weird-looking search results, odd indentation and broken stack snippets due to
$ being used in code. There are solutions to most of these, however. One solution is to escape all instances of
$ in code (like it's done with
>), which sounds fairly tedious but most of the work could automated if TIO were to do it. Not a great solution but some might believe having MathJax outweighs the cons.
We've had a lot of math questions (and answers) since and they would greatly benefit from having actual mathematical expressions that look ridiculously better than if they were done with meek markdown formatting.
I'd like to revisit this issue with another vote as opinions and ideas have changed since then.
Should MathJax be enabled again?
Please vote on the answers with approaches, not on the question based on your opinion on Mathjax.
