Processing \$ 123 \$ results in an unattended result.

[small-lovely-cat]

Issue Summary

When trying to process \$ 123 \$, the renderer returns 123 as inline formula, rather than the attended $123$

Steps to Reproduce:

See above.

Technical details:

The text is first processed by Parsedown (Markdown engine), then Mathjax.

• MathJax Version: 2.7
• Client OS: Windows 11 24H2
• Browser: Edge 133.0.3065.0

I am using the following MathJax configuration:

	MathJax.Hub.Config({ 
		tex2jax: {
			inlineMath: [["$","$"], ['\\(','\\)']],
			processClass: "classToProcess",
			ignoreClass: "classToIgnore",
		},
		skipTags: ['script', 'noscript', 'style', 'textarea', 'pre','code','a'],
		showProcessingMessages: false,
		messageStyle: "none",
		TeX: { equationNumbers: {autoNumber: "AMS"} },
	});

Even when adding processEscapes:true, nothing happened.

and loading MathJax via

<script src="https://cdn.bootcss.com/mathjax/2.7.0/MathJax.js?config=TeX-AMS-MML_HTMLorMML&noContrib"></script>

It seems that parsedown has some conflicts with mathjax.
Wondering if the problem still exists

Yes, Markdown of any flavor uses backslashes for its own processing (to prevent the usual effect of the following character), and usually that means that the backslash is removed and the following character is inserted into the HTML document without the backslash. That is likely the source of your problem. You might be able to use \\$ in your parsedown source in order to get \$ in the resulting web page (right now, you are just getting a $ without the backslash). You will probably need to add processEscapes: true to the tex2jax section of your configuration as well.
