    searchDisplay: Reset the keyboard focus after displaying async results
    
    We hide the content around displaying new search results to prevent
    flickering, unfortunately, one side effect of hiding an actor is
    losing key focus if it currently is on the that actor or any
    child. This could happen in the case of async results showing up after
    the user had moved focus to the search results.
    
    This patch works around that issue by saving the key focus and
    resetting it back after displaying the new async results.
