Fixes/improvements addressed to FocusZone:
chatBehaviorshouldResetActiveElementWhenTabFromZoneprop - when TAB fromFocusZone, give possibility to resetactiveElement. So when TAB back toFocusZone,activeElementwill be set to initial value, not where we left before. This behavior important for particular cases, for e.g., when usingVirtualListwe should always TAB back to last visible messageactiveElementfromdefaultTabbableElementprop toupdateIndexesmethod. Before it was incomponentDidMount, which would not always work in an exact time when we expect (when usingVirtualListitems are rendered with delay after FocusZone'scomponentDidMountwas called). Using itupdateIndexesmethod will assure that activeElement was initially set, so we can update tab indexes accordingly to it.TODO:
