Callout icons can't be suppressed in callouts without headings in HTML docs

[c-zippel]

Hi,
In HTML documents, setting the apperance="minimal" or icon=false attribute on a callout does not suppress the icon when the callout doesn't contain a header. Same goes for setting callout-appearance: minimal or callout-icon: false in the global options. This issue does not occur in PDF documents.

Reprex:

---
title: "Callout Icons"
format: html
---

::: {.callout-warning appearance="minimal"}

This is a callout without a heading. 

The icon is not suppressed.

:::

::: {.callout-warning appearance="minimal"}

# This callout has a heading. 

The icon is suppressed as expected.

Quarto Check

I'm not sure why the check could not locate R. I can run R code chunks in Quarto documents just fine.
