For a while we had either to render math outside of the forum or using some kind of ascii art for them.
But this is over now.
We added the offical math plugin to our instance. And yes asciimath is enabled too.
$$
E=mc^2
$$
will be rendered as
E=mc^2
All the rendering is client side (via javascript). Hope it makes it a bit more fun for you nerds.
The only caveat I have noticed so far that preview seems to act funky if you start directly with math.
Other than that my testing seemed to reveal no problems.
Yeah, I agree that \LaTeX is not the same as the standard typeset \LaTeX, which you’ve displayed. KaTeX (https://katex.org/) gets it right. Maybe it’s because we’re talking about math typesetting here, but this math plugin is giving us italics (i.e., \textit{\LaTeX}).
