navsets not rendering correctly with quarto

navsets are rendering correctly in rmarkdown but not quarto. The tab/pill/etc appears as plain html, regardless of which navset_* is used.

rmarkdown

title: "bslib rmarkdown"
output: 
  html_document:
    theme:
      version: 5

```{r message = FALSE}
library(bslib)
library(ggplot2)
library(plotly)

p1 <- ggplot(mpg, aes(displ, hwy)) +
  geom_point()
p2 <- ggplot(mpg, aes(cty, hwy)) +
  geom_point()

navset_tab(nav_panel(title = 'one', ggplotly(p1)), 
           nav_panel(title = 'two', ggplotly(p2)))
```

quarto

title: "bslib quarto"
format: html

```{r message = FALSE}
library(bslib)
library(ggplot2)
library(plotly)

p1 <- ggplot(mpg, aes(displ, hwy)) +
  geom_point()
p2 <- ggplot(mpg, aes(cty, hwy)) +
  geom_point()

navset_tab(nav_panel(title = 'one', ggplotly(p1)), 
           nav_panel(title = 'two', ggplotly(p2)))
```

Versions

• bslib 0.5.1.9000
• quarto 1.3.450

Reproduce the provided bslib examples in both R Markdown and Quarto using the listed versions, then compare their generated HTML and asset behavior. Done means the Quarto example renders navset tabs or pills as interactive components rather than plain HTML, matching the R Markdown result.
