We are using nested divs, and v0.2.261 seems to have broken our build.

With the following page:

```
# A title

::: {.callout-note}

::: {.another-div}
Some text
:::

:::
```

`quarto render` gives me:

```

```

There is no error if I change the initial div to something generic like `{.some-div}`.

v0.2.260 gives no error.
