Cross references broken inside math

[fulem]

Bug description

The cross reference system is broken inside math mode when we want to do theorem proving by equation chaining.

Reproduce:

# Test math and theorem proving

::: {#def-mydef}
This definition says that $A = B$.
:::

$$
  B = C 
$$ {#eq-myeq}

$$
\begin{align} 
     A \ &= B   &&, \text{ by } @def-mydef \\
         &= C   &&, \text{ by } @eq-myeq \\
\end{align}
$$

Outside math, references to @def-mydef and @eq-myeq work as expected.

More info:

• Quarto 1.2.280
• R studio 2022.12.0 Build 353
• Windows 11 Pro 22H2
