In the revealjs format, footnotes are not shown at the bottom of a slide when setting `scrollable` to `true`

[Mosk915]

I have:

• searched the issue tracker for similar issues
• installed the latest version of Quarto CLI
• formatted my issue following the Bug Reports guide

Bug description

In the revealjs format, when setting scrollable: true in the yaml, it is putting footnotes directly under the main content of the slide instead of at the bottom of the slide.

Steps to reproduce

---
title: "Footnote test"
format: 
  revealjs:
    scrollable: true
---

## Footnotes

Add footnotes like this^[Here is the footnote text]

Actual behavior

Footnotes are being displayed directly under the main content of the slide.

Expected behavior

Footnotes should be displayed at the bottom of the slide regardless of whether scrollable is set to true or false.

At a minimum, footnotes should be displayed at the bottom of the slide when scrollable is set to true but Scroll View Mode is toggled off in the Tools menu.

@Mosk915 please upgrade your version of Quarto CLI at least to the latest stable version before submitting issues, as you claimed you did when checking the box. Thank you.

Note that because the footnotes is part of the slide content and that you've set scrollable, it means there are no "bottom" of slide so the footnote goes at the bottom of the content.

@mcanouil Apologies for checking the box. I corrected the initial post. And thank you for the clarification. I will work with the current behavior.

[mcanouil]

Please don't close. It's possible there is a CSS trick that could be applied somehow.

Apologies for checking the box.

The "issue" is not the box but if you don't use the latest stable version it's more likely you'll face and report issues already solved in more recent versions thus why we request users to check that the issue appears at least in the current stable version.

@Mosk915 Instead of setting scrollable globally, you can set it on specific slides.

---
title: "Footnote test"
format: revealjs
---

## Scrollable Slide {.scrollable}

{{< lipsum >}}

Add footnotes like this^[Here is the footnote text]

## Default Slide {.smaller}

{{< lipsum 1 >}}

Add footnotes like this^[Here is the footnote text]

Note that what scrollable does, is changing the positioning of "aside" which can contain various things such as the footnotes.
In a non scrollable slide, the aside has position: absolute in order to get the footnotes at the bottom of the slide which has height and width set.
When scrollable is activated, position: relative is set otherwise the footnote would appear "at the bottom" but on top of the scrollable content.
