mathjax rendered outside post bodies

[bui]

eg. https://fgts.jp/_/search/username/%5B%24%24%24%20%2FHIS%2F%20ALLIANCE%20%24%24%24%5D/

unsure if this poses any sort of security risk, but shouldn't be happening either way

[Yarn]

in /assets/config/mathjax.js

changing the current config to skipTags: ["body"] and processClass:[ "text"] for each processor may work, that class name may be used outside of post text though

we also aren't using http://docs.mathjax.org/en/latest/safe-mode.html afaik so that should be added to the config too

i'm not even sure what the actual endpoint is for the config file though so who knows if any of that is right
