        Make <a> auto-close any parent <a> tag
        https://bugs.webkit.org/show_bug.cgi?id=41684

        I first fixed <a> to auto-close surrounding <a> tags.
        That caused about 3 more test passes and one new test failure.
        The test failure was due to <marque> not adding a marker
        to the active formatting elements.

        So I made a one-line change to fix <marque>.  However that hit an
        ASSERT due to a bug in indexOfFirstUnopenFormattingElement.
        Fixing indexOfFirstUnopenFormattingElement fixed another bunch of
        Adoption Agency related tests (clearly this was the second typo
        which was causing all the adoption agency failures).
        
        However fixing <marque> and indexOfFirstUnopenFormattingElement,
        added yet another failure due to missing support for </p>
        automatically adding an implicit <p> tag.  Fixing </p> finally
        got the tests to a stable (all improving) state.

        In the end, these 4 minor (and very well tested) tweaks fixed a total
        of 9 subtests in html5lib/runner.html.
        Another subtest progressed, but did not fully pass due to missing
        <table> foster-parenting support.
