    Treat ROLE_PAGE as a top-level object when doing Zombie checks
    
    In Evince documents, the page children of the document frame are
    sometimes reporting an index in parent of -1. Now that we're doing
    more aggressive checks for Zombies, this bug causes Orca to not
    present the content.
