   This violation also applies to .cell-output-display, the container for rendered cell output (tables, SVGs, widgets).

   At a 390 px viewport, a 10-column kable() is enough:

   ---
   title: "scrollable-region-focusable on cell-output-display"
   format:
     html:
       axe: true
   ---
   
   ```{r}
   knitr::kable(
     mtcars[1:6, 1:10]
   )
   ```

   axe 4.10 reports (Quarto 1.10.18, 390×844 viewport):
