    Click the button or the menu item for presentation on your browser (for example, "Cast"), <br>

    The test passes if a "PASS" result appears.

<p id="notice">
    If your browser does not support <code>defaultRequest</code>, please click this button: <button id="notsupported">Not Supported</button>
