    4. Otherwise, if the element being focused has an ID and the ID is referenced by the aria-activedescendant attribute of an element that is focusable, the user agent MUST set DOM focus to the element that has the aria-activedescendant attribute.

      An element with an ID can be referenced when it is owned by a container element that has the aria-activedescendant attribute or by a container element that is controlled by an element that has the aria-activedescendant attribute (e.g. see combobox). Otherwise the aria-activedescendant attribute reference indicates an author error.

      The inability to set DOM focus to the containing element indicates an author error.

    5. Otherwise, the user agent MAY attempt to set DOM focus to the child element itself.
