multiline formula support

[miptctx]

Latex has multline option to render formulas on few lines. Obsidian also support this option but flowershow doesn't. For example, this works in obsidian:

$$
\begin{multline}
some\ very\ very\ very\ very\ very\ very\ very\ very\ very\ very\ very\ very\ \\
very\ very\ very\ very\ very\ very\ very\ very\ long\ formula
b=c
\end{multline}
$$

And obsidian will draw such view:

But flowershow will not process this option correctly and it will make such view:

At the same time the split options works in flowershow, but this option does not render formula such perfect line multline does:

$$
\begin{multline}
some\ very\ very\ very\ very\ very\ very\ very\ very\ very\ very\ very\ very\ \\
very\ very\ very\ very\ very\ very\ very\ very\ long\ formula
b=c
\end{multline}
$$

This will give such view in flowershow:

Is it possible to add multline support?

Thanks.

@miptctx Unfortunately, it's not possible to add support for it. Flowershow uses KaTeX library to render LaTeX in the browser, and while it's primarily designed for LaTeX it doesn't support all the LaTeX syntax due to it's focus on performance.

But thank you so much for flagging this! Thanks to you, I realized the equations weren't even styled properly as I forgot to import KaTeX styles 🤦‍♀️.

@miptctx also, here is the full list of all supported functions: https://katex.org/docs/support_table
