  <meta name="assert" content="When set with 'overflow: hidden', an outer container must clip text of its child element at its corners. In this test, the outer container, which has immense size, has a 'border-radius' declaration which implies that the clipping must occur at its curve.">

  <style>
  body
    {
      overflow: hidden;
      /*
      otherwise, horizontal and vertical
      scroll bars will be generated
      */
    }

    {
      border-radius: 250em;
      color: red;
      font-size: 32px;
      height: 500em;
      overflow: hidden;
      width: 500em;
    }
  </style>

  <p>Test passes if there is nothing below.
