    appDisplay: Compare indicator and grid pages
    
    In the past, the icon grid would update the number of pages
    during the call to adaptToSize(). However, after the new grid
    layout landed, the number of pages is updated by the time an
    item is added or removed.
    
    Instead of comparing the old and new number of pages in the
    icon grid, compare the pages shown by the indicator, and the
    grid pages.
