Original issue's description:
> Uses the activedescendant_changed event received from Blink to fire the right focus event on the browser side.
>
> 1. Changed all <select> based widgets (list box role and menu list popup role) to fire activedescendant_changed events when the current selection changes. This behavior is the same as with ARIA combo boxes and other ARIA-based widgets that can have an active descendant. This means that we now have a uniform way of notifying the browser when the active child of a widget has changed.
> 2. Modified platform-specific code to fire the focus events on the active descendant when it changes, instead of relying on Blink.
> 3. Fires a focus event on the whole list or combo box when it collapses to make Windows screen readers enable their virtual cursor again.
