    Make ARIA gridcell cells caret-navigable if browse mode is sticky
    
    ARIA grids are expected to have author-provided navigation, just like
    ARIA's application role. When they don't, Orca's browse mode makes
    navigation via the arrows work in the manner expected to have been
    provided by the author. But that doesn't provide for caret navigation
    within a cell. We solved this problem for badly-authored application-
    role use by allowing sticky browse mode to let the user completely take
    over navigation. So do the same thing for grid cells.
