This tests that a top layer element is not rendered if it, or an ancestor, has display: none.
It passes if you see a green rectangle stacked on top of a blue rectangle, and see no red rectangles.

<div class="pseudodialog" style="top: 50px; background-color: blue"></div>
<div class="pseudodialog" style="top: 100px; left: 50px; background-color: green"></div>
