`equation` environment under `$$`

[likanzhan]

Bug description

My qmd file contains a julia code cell, and the output of the cell is a equation environment.
When I rendered it into a html file, it works correctly.
But when I rendered it into a latex file, it creates a latex file with the following environment

$$
\begin{equation}
ZZZ
\end{equation}
$$

When I render a latex file containing such blocks, it gives an error.

Steps to reproduce

```{julia}
using Symbolics
Symbolics.variables(:x, 1:3)
```

Expected behavior

\begin{equation}
\left[
\begin{array}{c}
x_1 \\
x_2 \\
x_3 \\
\end{array}
\right]
\end{equation}

Actual behavior

$$ \begin{equation}
\left[
\begin{array}{c}
x_1 \\
x_2 \\
x_3 \\
\end{array}
\right]
\end{equation}
 $$

Symbolics.jl/Jupyter is the one emitting this bad code.
