Bug: Incorrect rendering of text containing "$"

It looks to me like the wallabag UI reader is doing markdown-style latex interpretation of text between $ symbols, but $s aren't being escaped when read in literally.

Hello @GiovanH,

It looks like this comes from MathJax integration

I am wondering how this happens since the dollar sign $ is not a math delimiter in MathJax by default and as described in #7389 I only get MathJax rendering using \( and not $.
