<h1>Click targeting when targets of down and up are child and parents</h1>
This test verifies that click event always goes to the first common ancestor of down and up event targets.
<ul>
<li>Press down the primary button on link 1 and move onto green container and release.</li>
<li>Press down the primary button on red container and move onto link 2 and release.</li>
<li>Click done.</li>
