Describe the bug

When viewing the chapter listing of a book, I've noticed that some code can be incorrectly parsed as LaTex. In my minimal reproducible example, I've created a page that contains nothing but a title, brief summary, and a code block containing a regular expression.

This displays fine at the page level, but displaying within the page listing causes the contents to display as LaTex.

Steps To Reproduce

Steps to reproduce the behavior:

Create a new page.
Fill the title
Put a code block towards the very top and fill it with text like (\[A-Z\]\[a-z\]+)+Exception
View the page in the chapter listing.

Expected behavior

No LaTex parsing.

Screenshots

Page content and display:

Incorrect page listing

Your Configuration (please complete the following information):

Exact BookStack Version (Found in settings): v21.05.1
PHP Version: 7.3.27
Hosting Method (Nginx/Apache/Docker): docker - linuxserver/bookstack

Shortly after producing the MRE and posting here, I remembered I added the custom header below to more easily display math in my notes... so I guess this is my fault. As this doesn't present problems at any other point, I would like to raise the suggestion that we leave the code block tags within the page listing.

<script type="text/javascript" id="MathJax-script" async
  src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js">
</script>

Hi @jacobm001, I will therefore close off this issue since we don't do any LaTex parsing by default in BookStack.

I would like to raise the suggestion that we leave the code block tags within the page listing.

I wouldn't want to go down that path as it'll greatly complicate the logic to truncate the content at a fixed length. I think the best way to solve this would be to configure MathJax to only parse within page content (And not all parts of the UI). From my quick testing I believe this can be achieved by adding something like the below before your MathJax script:

<script>
window.MathJax = {
  startup: {
    elements: ['.page-content']
  }
};
</script>

From my quick testing I believe this can be achieved by adding something like the below **_before_** your MathJax script: ```html <script> window.MathJax = { startup: { elements: ['.page-content'] } }; </script> ```

That, actually solved my problem completely. Thank you.
