page_fillable leaves a gap on the bottom on Windows

The following code:

library(shiny)

ui <- bslib::page_fillable(
    padding = 0,
    bslib::card("test")
)

server <- function(input, output, session) {}

shinyApp(ui, server)

results in whitespace below the card, which only gets fixed if I add gap=0. This is happening with {bslib} 0.6, 0.7 and 0.8. I'm on Windows. I updated to the latest {shiny} and {htmltools} and it still happens.

When I run the same code on https://shinylive.io/r , it does not happen

Thanks, which browser (and version) are you using?

Does it reproduce for you in Chrome 127?

Chrome doesn't make it easy to find older versions, but I had Edge with Chrome 125 installed in my Windows 11 VM. I can't reproduce the issue with Chrome 125 (in Edge) or Chrome 127.

Are there any hints when you inspect the DOM?

We do have an <svg> element that will be a sibling of the card element, but it should have both positon: absolute (moving it out of the document flow) and aria-hidden="true" (removing it from the accessibility tree, too). It'd be strange if that were causing the problem, but worth taking a look at it.

Ah, the loom extension adds an element...
