You should see a 100x100 green square below. If you see nothing at all or see any red, the test
has failed. This test is checking to make sure overflow is done using
a containing block model, and that a fixed positioned element inside another fixed positioned
element is not considered overflow.
<div class="overflow positioned">
<div class="red"></div>
<div class="green positioned"></div>
