    <meta name="assert" content="A value of 'auto' for 'left' in the rect
    function is equal to the top edge of the border box. The box shadow should
    be clipped, since it is painted outside the border box. On pass you should
    see a vertical green stripe on the right side of a vertical blue stripe.">

    <p>The test passes if there is a vertical green stripe on the right side of a vertical blue stripe.</p>
