bug: quarto doesn't respect fenced divs for callouts in commonmark

[JosiahParry]

Description

Quarto doesn't respect fenced divs when rendering to commonmark with commonmark output. Note that pandoc does correctly handle this.

Given a qmd file like this

---
title: example
format: commonmark
---

::: callout-note
This is a callout not getting fenced div class
:::

then running quarto render test.qmd creates

# example


<div>

> **Note**
>
> This is a callout not getting fenced div class

</div>

when it should create

# example


<div class="callout-note">

This is a callout not getting fenced div class

</div>

Note that pandoc works here:

blog-zola ⚡ pandoc test.qmd -t commonmark -f markdown
<div class="callout-note">

This is a callout not getting fenced div class

</div>
