Active Dropdown item should be scrolled into view on open

[levithomason]

Steps

1. Set selectOnBlur={false}
2. Make an item active.
3. Scroll the dropdown so it is out of view.
4. Close the dropdown.
5. Open the Dropdown.

Actual

The Dropdown does not show the active item because it persists its scroll position, so the active item is still out of view.

Expected

Opening the dropdown should always show the active item. Otherwise, users are confused by what they see.

Fix

There is already a method to scroll the active item into view. We simply need to call it on open.
