Describe the bug

When a LaTeX math block contains = on a standalone line, the image fails to render. Moving = to the same line as other content fixes the issue.

Steps To Reproduce

Not working:

$$
\begin{bmatrix}
1 \\ 2
\end{bmatrix}
=
\frac{1}{2}
\begin{bmatrix}
2 \\ 4
\end{bmatrix}
$$

Working:

$$
\begin{bmatrix}
1 \\ 2
\end{bmatrix} =
\frac{1}{2}
\begin{bmatrix}
2 \\ 4
\end{bmatrix}
$$

Expected Behavior

= on a standalone line,

Repro

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

require("lazy.minit").repro({
  spec = {
    { "folke/snacks.nvim", opts = {} },
    -- add any other plugins here
  },
})

I don't do latex, so feel free to create a PR

[junyixu]

Likely related to how treesitter extracts the math content from the $$ block. When the = is on its own line, it may be creating a parsing boundary that causes the displayed equation node to be split or captured incorrectly.

[junyixu]

A possible workaround would be to add a preprocessing step that normalizes standalone operators on their own lines. Not sure
