This PR makes several changes to focus-zone:
signal
to several event listeners where it is currently missing.clearActiveDescendant
to loop over all child elements with thedata-is-active-descendant
attribute and removes it from each. The current behavior only removes the attribute from a single element, which is a problem in React apps because React re-uses elements with the same key, resulting in more than one element being marked as the active descendant.
