    appDisplay: Don't update multiline for search results
    
    The grid icons in the search results page doesn't expand to
    acommodate the multiline label, resulting in the multiline
    label to overflow behind the list search results. However,
    after 548d3b62d, it was possible to trigger this behavior
    with keyboard focus.
    
    Don't update multiline labels for search results.
