| This tests that calling <code>document.elementFromPoint()</code> on an element displayed in a region's |
| hidden overflow will not return that element (but the element "underneath" it).<br> |
| You should see "PASS" being displayed below. |
| <div id="content"><span class="spacer"></span>This text has <span class="highlite">overflow</span></div> |
| <div id="result"> </div> |
| <div id="parent"> |
| <div id="region"> |
| <p></p> |
| </div> |
| </div> |
| <script type="text/javascript"> |

| |
| fromSelector = document.querySelector(".highlite"); |
| fromPoint = document.elementFromPoint(boxLocation.left + boxLocation.width/2, boxLocation.top + boxLocation.height + 35); |
