There was a problem hiding this comment.
We definitely should start extracting behavior for the Dropdown component, we have too much coupling of accessibility concerns in the component... That way we would test this things separately.

Without it, when in a Popup and a selected item is focused, shift tab will make focus escape the Popup, as FocusTrapZone will not handle it as first focusable item in the Popup (due to the lack of tabindex="0").
Also it does not hurt to be able to come back to the selected item via tab/shift tab once you tabbed/shift tabbed away.
