how to auto-number and quote math formula?

[dualer]

Summary

I have a very basic question: how can we auto-number and quote math formulas through this extension? I find katex is supported to auto-number math formulas, but mdmath seems to don't support it. As for quoting math formulas, I cannot find how to do this, the following code don't work:

$$
\pi \tag{1}\label{1}
$$

eq.$\eqref{1}$

...

Expected behavior

...

Actual behavior

...

Steps to reproduce

1. First step
2. Second step
3. Third step

Code example

Some markdown code ...

... with issues.

I use align environments to get eq numbering.

$$
\begin{align}
f'(x) &= \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}
\end{align}
$$

Edit: I just tried using a label, but it renders with an error. It could be I haven't got amsmath to use it.

Are you sure? It doesn't work for me.

@carneeki When I disable the related function of markdown math, it works. Thanks for your detailed explanation.

I added the following settings into my VSCode settings.json, and it seems rendering fine in the preview.

"mdmath.katexoptions": {
    "trust": "(context) => ['\\htmlId', '\\href'].includes(context.command)"
},
"mdmath.macros": {
    "\\eqref": "\\href{###1}{(\\text{#1})}",
    "\\ref": "\\href{###1}{\\text{#1}}",
    "\\label": "\\htmlId{#1}{}"
},
