<li>Use your mouse to drag the orange box over a part of the taskbar that overlays the blue part of this page.</li>
<li>If supported by the platform, the mouse cursor should <em>not</em> show the browser's custom "copy" cursor, and should instead show the system's expected cursor for dropping on that part of the taskbar.</li>
<li>Release the drag. Fail if the text on this page changes.</li>
<li>Reload and repeat this test for:<ul>
<li>Where the blue part of this page extends under an always-on-top window (eg. the Windows Task Manager).</li>
<li>Where the blue part of this page extends under an always-on-top notification (eg. a system tray info balloon).</li>
