The test passes if you see a 600x300 blue rectangle.

<div style="display: flex; flex-direction: column; width: 600px;">
  <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 200 100" data-expected-bounding-client-rect-width=600
    data-expected-bounding-client-rect-height=300>
    <rect x="0" y="0" width="200" height="100" fill="blue" />
  </svg>
</div>

<script>
  checkLayout('svg');
