`renderthis::to_pdf()` is unable to capture footnotes from Quarto presentation

Hi,

I am using renderthis_0.2.0 and Quarto version 1.2.269

I have created a Quarto script called index.qmd that has the one title slide followed by one content slide. I tried to add an aside and footer on the content slide

---
title: "Title"
author: "Name"
format: 
  revealjs:
    navigation-mode: linear

## Quarto

Quarto enables you to weave together content and executable code into a finished presentation. To learn more about Quarto presentations see <https://quarto.org/docs/presentations/>.

::: aside
Some additional commentary of more peripheral interest.
:::

::: footer
My footer
:::

I have rendered the file to index.html and tried to convert it to pdf using the command

renderthis::to_pdf("index.html")

When I take a look at the pdf file, the content slide seems to have lost the footer but the aside can be seen.

For reference, this is how it looks like in html

and in pdf

Hope this is reproducible from your end.

Reproduce the issue with the provided index.qmd, rendered index.html, and renderthis::to_pdf("index.html") command, then compare the HTML and PDF slides. Done means the footer shown in the Quarto presentation is retained in the generated PDF while the aside continues to render.
