revealjs speaker view lightbox activation doesn't propagate to presentation view

Start by compiling the provided Quarto revealjs presentation with lightbox: auto, then inspect how Quarto supplies its reveal.js dependency and compare it with the referenced reveal.js fix. Update the dependency to at least 5.2.1 and confirm that activating lightbox in speaker view also activates it in the fullscreen presentation view.

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

Issue described in https://github.com/hakimel/reveal.js/issues/3771
Fixed in https://github.com/hakimel/reveal.js/commit/aa9dfc7eb833c8d2f1eee437be950d5627c99d87
Updating reveal.js dependency to ≥5.2.1 should fix

Steps to reproduce

1. Compile this presentation:

---
title: "Untitled"
format: 
  revealjs:
    lightbox: auto
---

## Quarto

```{r}
plot(1:10)
```

2. Start speaker view

3. click the plot to turn on lightbox

4. Observe the fullscreen view does not change

Actual behavior

Lightbox does not engage in the fullscreen view

Expected behavior

The fullscreen view and speaker view should stay synced
