   <title>Testcase for child &lt;svg&gt; with viewBox</title>

   <!-- From https://bugzilla.mozilla.org/show_bug.cgi?id=369402

        The presense of the viewBox attribute below should not be stopping the

        lime rect from rendering. (The preserveAspectRatio is only there to make

        the lime rect fully cover the red rect on success. It is not the problem.)

   -->

   <rect width="100%" height="100%" fill="red"/>

   <svg viewBox="0 0 100 100" preserveAspectRatio="none">

     <rect width="100%" height="100%" fill="lime"/>

   </svg>
