    Web: Don't announce unselected state of grid cells/rows in browse mode
    
    If we're in browse mode in a grid, the user has presumably chosen to
    review the contents rather than interact with them using author-provided
    navigation and associated functionality. As such, tacking on "not selected"
    for each gridcell is not especially helpful.
