<html><body>
This tests behavior of "noreferrer" links in subframes. A referrer should not be sent and window.opener should remain null.<br/>
<a id="link" href="resources/no-referrer-helper.php" rel="noreferrer" target="subframe">Load subframe</a>
<iframe name="subframe" src="about:blank"></iframe>

    var target = document.getElementById("link");
    eventSender.mouseMoveTo(target.offsetLeft + 2, target.offsetTop + 2);
