Defining macros per [docs](https://quarto.org/docs/authoring/markdown-basics.html#equations) like

```
::: {.hidden}
$$
 \def\RR{{\bf R}}
 \def\bold#1{{\bf #1}}
$$
:::

$$\RR$$
```

Does not work with Revealjs. The output is simply `\RR`.  The same occurs when using a hidden slide, e.g. 

```
## Setup {visibility="hidden"}
$$
\def\RR{{\bf R}}
\def\bold#1{{\bf #1}}
$$

## Title
$$\RR$$
```

However, doing
```
## Title
$$
\def\RR{{\bf R}}
\def\bold#1{{\bf #1}}
$$

$$\RR$$
```

Does work.
