revealjs: footnotes always appear despite pauses

Bug description

I have a slide where I show two steps with a pause between the two. If I add a footnote in the second step, it is displayed from the beginning whereas it should appear only in the second step.

Example:

---
format: revealjs
---

First step.

. . .

Second step^[This footnote shouldn't appear in the first step.]

RStudio 2022.07.1+554 "Spotted Wakerobin"
quarto v. 1.2.157
Windows 10 x64 (build 19044)

Checklist

• Please include a minimal, fully reproducible example in a single .qmd file? Please provide the whole file rather than the snippet you believe is causing the issue.
• Please format your issue so it is easier for us to read the bug report.
• Please document the RStudio IDE version you're running (if applicable), by providing the value displayed in the "About RStudio" main menu dialog?
• Please document the operating system you're running. If on Linux, please provide the specific distribution.

Start with the provided single .qmd reproduction using the revealjs format and inspect how the footnote in the second step is rendered across the pause. Reproduce the issue, then verify that the footnote is hidden during the first step and appears only during the second.
