Different math behavior in HTML and DOCX

Bug description

It seems like DOCX files need math to be surrounded by ``$$ ... $$` while HTML documents do not. It is counterintuitive to me that the way Quarto expects math to be written depends on the output.

Steps to reproduce

---
title: "Math Quarto test"
format:
  docx:
    toc: false
  html:
    toc: false

---


\begin{align*}
  \text{Equation 1}
\end{align*}

$$
\begin{align*}
  \text{Equation 2}
\end{align*}
$$

Expected behavior

I expect that both equations will display in the HTML and DOCX outputs.

Actual behavior

Only the HTML displays both equations. The DOCX only displays the equation when surrounded by $$ ... $$.

Start with the provided minimal Quarto reproduction and compare how Pandoc processes the two math forms for HTML and DOCX output. Done means both equations render in both formats without requiring different source syntax.
