    - updated some more only-child and only-of-type tests to expect success
          (failures seen on buildbot)

        The tests were now succeeding, but the results and placement reflected failure.
        I'm not sure why we have such a tiny set of tests in the css3 directory.
        The expected results are updated as well as moved.
