Issues for TeX expressions using percentages (%)

[Masstronaut]

Just checked out latest per our discussion in the MDsveX issue. It seems to have issues with rendering the % character. for example:

$5\%$
$$
5\%
$$

Produces the error

LaTeX-incompatible input and strict mode is set to 'warn': % comment has no terminating newline; LaTeX would fail because of commenting the end of math mode (e.g. $) [commentAtEnd]

And fails to render the % character despite it being escaped which AFAIK (I'm not TeX expert) is the correct way to do it. I see the following rendered output:

This output makes sense if it's treating the % characters as a comment, rather than treating the escaped \% as a percentage character. Given the errors, I think that scenario is likely.

I've investigated this further and it seems the issue is actually occurring upstream in another step of my processing pipeline - discussion here. I'll go ahead and close this issue as it doesn't appear to be rooted in rehype-katex-svelte
