Summary AX: active descendant not exposed when isolated tree mode is on

To repro, visit Kayak.com and click on the Round-trip combo box. VoiceOver focuses on the listbox that pops up, but usually (not always) fails to interact with the active option. If you manually check the accessibility API at that time, the list box usually (but not always) returns nothing for the active descendant, even though inspecting the DOM shows it's set. If you arrow to another option, the active descendant starts working. With ITM off it works correctly every time.
