Scidown does not render labeled LaTeX equations with MathJax

[N0rbert]

Scidown is a dependency of Marker.
As the result Marker can't render the following LaTeX equations by MathJax engine:

LaTeX equation (`\begin{equation}...\end{equation}`)

\begin{equation}
h(z) = \sinh(z)
\end{equation}

---

LaTeX equation with `\begin{equation}...(\#eq:label)\end{equation}` RMarkdown + bookdown syntax (see [this chapter](https://bookdown.org/yihui/bookdown/markdown-extensions-by-bookdown.html#equations)):

\begin{equation}
  f\left(k\right) = \binom{n}{k} p^k\left(1-p\right)^{n-k}
  (\#eq:binom)
\end{equation}

---

LaTeX equation with `\begin{equation}...\label{label}\end{equation}` label for [xaringan](https://bookdown.org/yihui/rmarkdown/xaringan.html)

\begin{equation}
  g\left(k\right) = \binom{n}{k} p^k\left(1-p\right)^{n-k}
\label{binom2}
\end{equation}

The ReText editor also uses MathJax, but renders these equations normally:

Please add support for the equation syntax to SciDown.
