    <p>Test for iframe flattening. The flattening only works inside the DRT.
    <p>This inner frame should be 400px in each direction, disregarding the
       border, and it must not be scrollable or have scrollbars.

    <p><iframe width="200px" height="20%" scrolling=auto src="data:text/html,
        <style>body { background-color: red; }</style>
        <body>
            <div style='position: absolute; width: 400px; height: 400px; left: 0; top: 0px;'></div>
