Description

Bug description

I am struggling to label multiple equations placed within $$ \begin{align} ... \end{align} $$.

This works flawlessly...

$$
\begin{align}
a &= 0+1 \\
b &= 2+3 \\
c &= 4+5
\end{align}
$$ {#eq-abc}

see @eq-abc.

...but neither of these work:

$$
\begin{align}
a &= 0+1 \label{eq:a} \\
b &= 2+3 \label{eq-c} \\
c &= 4+5 {#eq-d}
\end{align}
$$

I tried various other versions of Quarto and/or LaTeX syntax, but couldn't achieve the desired results: To have multiple numbered (and cross-referenceable) equations placed within an align-block.

Any suggestions would be greatly appreciated! And, it would be nice to have such an example included in the Equations sections of the Technical Writing documentation here.
