<p>This tests that when setting the height of a flex item to a percentage
height, we use the content height with scrollbars. The content should not be
scrollable in any of the test cases below.</p>

<div class="flexbox column">
  <div style="height: 100%"></div>
</div>

<div class="flexbox column">
  <div style="height: 100%; box-sizing: border-box; border: 5px solid green"></div>
</div>

<div class="flexbox column wrap">
  <div style="height: 50px; width: 50%;"></div>
  <div style="height: 50px; width: 50%; background-color: lightblue"></div>
</div>
