  .clipped {

    width: 50px;

    height: 50px;

    background-color: green;

    clip-path: margin-box;

    border-radius: 10px;

    /* This outline draws far outside the margin box and should be partially clipped. */

    outline: 200px solid green;

    margin: 50px;

    /* Disables margin collapsing. */

    float: left;

</style>

<!--

  Spec: If the ratio of border-radius/margin is less than 1, and margin is

        positive, then the margin box corner radius is

        border-radius + margin * (1 + (ratio-1)^3).

  This test has a border-radius of 10 and a margin of 50, and should use a

  margin box corner radius of: 10 + 50 * (1 + (10/50-1)^3) = 34.4
