Make selected item get focus when dropdown is opened (#43722)

As it stands, dropdowns currently do not focus the item that is selected, so if you select something on a dropdown, and then close it, and re-open it, then the new item is not auto-focused. This PR changes that so that selected value is focused by default when the dropdown is re-opened.
