HTML output with quarto and tikz too small and not cross-referenced

[amael-ls]

Hello, I am having two problems with diagram converting a tikz figure within a quarto document:

1. The font of the html output is too small (but is of normal size in pdf output)
2. The reference does not work for both html and pdf output

Here is a MWE:

---
title: "A tikz diagram extension test"
filters:
  - diagram

## Test section

Hello, please see \ref{fig-delta} and @fig-delta

```tikz
%%| label: fig-delta
%%| caption: A test
\begin{tikzpicture}
	\node (a) at (0, 0) {a};
	\node (b) at (2, 0) {b};
	\draw (a) -- (b);
\end{tikzpicture}
```

And here is the output (I am using firefox)

In Quarto 1.4, there were changes to how labels and captions work.

You need to wrap the figure in ::: with the first one having the figure id, e.g. ::: {#fig-delta} and the optional caption comes just before the end :::
