Reproduction

Don't really have the time to make one right now, but am willing to.

Describe the bug

With Content V2, installing remark-math and rehype-katex allows for math blocks to be treated LaTeX expressions and rendered as such.

With Content V3, such blocks as forcefully rendered as ProseCode despite both remark-math and rehype-katex being present. (dollar sign delimited math blocks still render fine)

Additional context

Happens with Content V3 only.

Math fence blocks:

**The Cauchy-Schwarz Inequality**
```math
\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)
```

The Cauchy-Schwarz Inequality

$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$

Math dollar sign delimiters:

$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$

The Cauchy-Schwarz Inequality
$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$
