  <meta name="assert" content="This test verifies aspect-ratio's <ratio> is used to determine the canvas' size because contain:size enforces no intrinsic aspect ratio.">

  <style>
  canvas {
    width: 100px;
    aspect-ratio: 1/1;
    contain: size;
  }
  </style>

  <script>
  window.onload = function() {
    const canvas = document.querySelector('canvas');
    const ctx = canvas.getContext('2d');
    ctx.fillStyle = 'green';
    ctx.fillRect(0, 0, 200, 200);
  }
  </script>

  <p>Test passes if there is a filled green square and <strong>no red</strong>.</p>
  <canvas width=200 height=200></canvas>
