        Test: fast/forms/slider-hit-testing.html

        We need to clear m_overflow otherwise we use the first
        size of the slider for hit testing (i.e., changes to the size
        cause problems).  This only shows up if the thumb isn't contained
        in the bounds of the slider.  Making the range have a smaller height
        than the thumb shows the bug.

        * rendering/RenderSlider.cpp:
        (WebCore::RenderSlider::layout): Clear the overflow during layout
            so we re-compute the overflow based on the current size of the
            slider.
