Callout in revealjs slide with smaller class get unaligned title

[cderv]

This is because of the .smaller effect on the slide applying to the callout titles.

There is probably a css rule to tweak to avoid this

[cderv]

From #9549, the SCSS variables for font-size has no effect on the icon, which leads t be bad results

Given an index.qmd

---
title: reveal callouts
format:
  revealjs:
    theme: [simple, custom.scss]
---

## what

::: {.callout-warning}
you need to see this.
:::

and a simple custom.scss

/*-- scss:defaults --*/

$presentation-font-size-root: 28px;

/*-- scss:rules --*/

This is because we use PNG for the icon, and not SVG like in HTML
