Sidebar in Dashboard not toggleable anymore with `{bslib}` value box

Bug description

I used bslib::value_box() to add a value box to a Quarto dashboard due to better customizability (see also #9453). But this means sidebars cannot be toggled anymore after adding the value box. My guess is that something about the value box's full screen mode (that is available in the Quarto dashboard even though this option is set to FALSE) prevents the moving in and out of the sidebar. But this is just a hunch.

Steps to reproduce

---
format: dashboard
---

# Page 1

## {.sidebar}

This sidebar is not toggleable anymore

## Main body

### Value box

```{r}
bslib::value_box(
  'Adelie penguins',
  theme = "danger",
  value = 23432,
  full_screen = FALSE ## This is nevertheless possible in the dashboard 
)
```

Expected behavior

Sidebar moves in and out after clicking on the arrow thingy

Actual behavior

Side doesn't move
