### Bug description

I can't reproduce an example in the Quarto [documentation](https://quarto.org/docs/interactive/layout.html). The example shows how to change the layout of input filters so that the filters are next to each other. When I try to reproduce this, the inputs are below each other.  I am on Windows and am running the RStudio version 2022.07.1 Build 554

viewof rng = Inputs.range(

  value: 3,
