### 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:
```rmd
---
format: revealjs
---

First step.

. . .

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