To Reproduce
Steps to reproduce the behavior:

1. Have a question that uses $ in someway
2. Sometimes it'll look funny, and I'm pretty sure it's cause it's getting LaTeX

Expected behavior
The text to be rendered plainly

Additional context
I've seen this a number of times but never gotten around to digging into it, but am finally getting around to making an issue and will try to dig into it next month, maybe 😅

I've not yet actually dug into the reproduction but after seeing e9a1a0e#diff-b2f6cda8173123dbe9526a48f2ed496680a0acee69c555940da10e1e0fd2c9bdR34 and how this presents, I'm pretty sure this is the LaTeX support being bugged

@tylerbwong I had an initial look at this and it seems that LaTeX is actually only supported on the Math exchanges so I think part of the solution here would be to restrict when LaTeX is actually supported.

My ideas for that are:

• disable/enable for questions from the math exchanges specifically
• have a list of exchanges as a setting, which included the math exchanges by default but meant users could add additional exchanges (and maybe stuff like beta sites?)
• have a single global setting that users could toggle based on their preference

While that last one is the least ideal, I would expect it to be the easiest to implement and would really help users like me who are more interested in 98% of the other stackexchanges.

Unfortunately, I've not been able to figure out how to do any of these as it looks like the processing happens via a plugin and that the markdown renderer is injected from another package? it seems very reasonable, but I couldn't figure out how to approach making a plugin conditional based on question data.

I'm happy to have a crack at this but at this point would need some pointers from you as to where to look.

Note I've not looked much into the actual LaTeX side of things - I suspect based on this & #107 that there is something buggy there, and it could be that the matcher is not following the spec, but I wouldn't be surprised if that's a longer piece of work than what I've described above; still happy to look into that too if you'd prefer.
