The auto-render extension will render the following environments even if they are not inside math delimiters
such as
$$…$$. They are display-mode only.
\begin{equation}
\begin{split} a
&=b+c\\
&=e+f
\end{split}
\end{equation}
\begin{align}
a&=b+c \\
d+e&=f
\end{align}
\begin{gather}
a=b \\
e=b+c
\end{gather}
\begin{alignat}{2}
10&x+&3&y=2\\
3&x+&13&y=4
\end{alignat}
\begin{CD}
