Hello! Running latest RStudio preview build (2022.02.0 Build 442). Trying to use Quatro to build a reveal.js presentation. Unfortunately, the auto-animation-duration option in the preamble doesn't seem to be doing anything. 

Toy example: 
```
---
title: "Practice"
author: |

format: 
  revealjs: 
    auto-animate-easing: ease-in-out
    auto-animate-duration: 10
    theme: solarized
editor: visual
---

## Test slide

::: {.fragment .fade-in}
::: {.fragment .highlight-red}
::: {.fragment .semi-fade-out}
Fade in > Turn red > Semi fade out
:::
:::
:::
```
