Luckily, Typst actually has experimental HTML export which is progressing quite nicely (even with MathML in the next update!), see here: https://typst.app/docs/reference/html/

Admittedly, not the most renowned or most known journals but you have to start somewhere.
I don't always understand all of it but I trust and know that care has been taken to properly validate all of those changes, partially thanks to all the unit/integration tests we have.
The thing is, inserting PDF for just the PDF export would be quite easy. The issue is the other export targets Typst supports (SVG and PNG) as that would require some form of rasterization / a full blown PDF engine written in Rust without C-bindings because of the web app and that simply does not exist yet.
And the developers are hesitant to just add features for one specific export target which I get.
Maybe there are add-ons that detect valid LaTeX math symbols and convert them whenever possible but as-is you can't get it to render within the comments.
From what I understand, just \nabla(f) describes the gradient of a function f -- meaning all the first order partial derivatives (of a certain point) in a vector.
\nabla * f describes the divergence of the function f -- meaning a scalar field of the quantity of the vector field's sources at each point.
\nabla * \nabla(f), divergence of gradient, then describes the Laplace operator. Also written as \nabla^2(f) or \Delta(f) -- note that it's an uppercase delta.
