  #test contains both inline-level contents (the canvas) and block-level (the <p>).
  Then the canvas is wrapped inside an anonymous block, but it still resolves its percentage against #test.
  So the canvas is 100px tall, and thus 100px wide because of its aspect ratio.
  Therefore #test is 100px wide too.
">
<style>
#test {
  display: inline-block;
  height: 100px;
  background: green;
}
#test > canvas {
  height: 100%;
  background: red;
  position: relative;
  z-index: -1;
}
</style>

<p>Test passes if there is a filled green square and <strong>no red</strong>.</p>
<div id="test">
  <canvas width="10" height="10"></canvas>
  <p></p>
