Tell us about your environment

macOS 15.3.2

MarkBind version

Describe the bug and the steps to reproduce it

Important: Add the following to site.json to activate \begin{} ... \end{} environment.

{
  "plugins": [
    "mathDelimiters"
  ],
  "pluginsContext" : {
    "mathDelimiters" : {
      "delimiters": ["beg_end"]
    }
  },
}

Afterwards, test the rendering of

\begin{align*}
  x^2 + y^2 &= 1 \\
  y &= \sqrt{1 - x^2}
\end{align*}

and you can see that this block is not recognized as Tex.

Expected behavior

Such environments should be correctly parsed and rendered as an unnumbered tex block.

Anything else?
