when using typst in titles, it's not rendered as big as it should be

# Big Theta - $Theta$

Not sure if this really is a bug or working as intended. Math blocks have no context of where they are, so extra styling is incredibly difficult to apply. We could get more context by using a codemirror extension but I haven't found a way to completely stop Obsidian's own math blocks.

i mean the built in latex math blocks work fine in titles so i definitely think this is a bug

Hi I'm doing similar thing last week(rendering typst to svg and embed them in markdown). To solve this you need to adjust the svg: by changing the unit of its height and width to em, the svg will automatically scale itself according to the font size.

Code here: https://github.com/Myriad-Dreamin/typst.ts/blob/main/projects/rehype-typst/lib/index.js#L116

And this is how it looks like

Also I see currently the css is set to

.typst-doc {
    vertical-align: bottom;
}

There can be better control of this by querying the location of text baseline in typst and set vertical-align according to it.

I guess the optimize svg thing is no longer needed too because currently typst use a stable id to name glyphs so there is no collisions now.

I guess related is:

some vec $vec(1,2,3)$.

renders as

meawhile without the plugin this

some vec $\begin{pmatrix}1\\2\\3\end{pmatrix}$.

renders as

As of version 0.9 the output SVG's size is in em which should scale with the font size of the line it is on including headings. This does highlight another issue of the base line but that should be discussed in a new issue.
