    <title>CSS Test (Transforms): Backface-Visibility With Transformed Parent
    in Different Rendering Context</title>

    <link rel="help" href="http://www.w3.org/TR/css-transforms-2/#propdef-backface-visibility">
    <meta name="assert" content="This tests that if an element is not
    transformed, but its parent is rotated 180deg in a different rendering
    context, the child's 'backface-visibility: hidden' does not make it
    disappear.  Only transforms that affect the child itself are relevant to
    'backface-visibility'.">
