[gtk/matthiasc/css-change-tracking-4: 8/11] Add another testcase for change flags

[Matthias Clasen <matthiasc src gnome org>]

    Add another testcase for change flags
    
    This one shows cases where I think the superset matcher
    should be more precise and not include these selectors,
    since the node tree can't actually match them.
