How can I synchronize code animations with other fragments?

Description

Based on this discussion on the revealjs repo, it seems this should be possible. Here's what I tried:

## Demo

```{.sh code-line-numbers="1|2|3" fragment-index="1" }
first
second
third
```

::: {.fragment fragment-index=1}
- Don't do this
:::

::: {.fragment fragment-index=2}
- or this
:::

But this leads to 2 empty animations, then lines 2 and 3 of the code, then the two bullets.

Note: I can get what I need using multiple slides and auto-animate, but it would be nice to have less boilerplate to make it work

I believe there is a feature request related to that .
