How to show scrollbars in Combobox

[NilsEvers]

I want to restrict the height of the ComboBoxViewport and allow the content to scroll.
This works but the scrollbars are hidden because the ComboboxViewport sets the scrollbar-width to none.
This behaviour is inline with the ScrollArea component however here I cannot use the ScrollAreaScrollBar component.

What is the best way to solve this?

You can simply manually add scrollbar-width in the ComboboxViewport:
<ComboboxViewport style="scrollbar-width: thin">
