onbeforeunload event on iframe is not triggered in google chrome, works in IE, firefox

If you set an unbeforeunload event inside an iframe, this is not triggered when you for instance click through to a link in the iframe. It works in IE and Firefox (not Opera, but Opera does not support onbeforeunload in general AFAIK).

Just wondering, am I doing something wrong? Should this behaviour not be possible? Or is it a bug in Google Chrome/webkit? Any workarounds?

Code example:

test.html:

<html>
  <body>
    <p>Main page content</p>
    <script type="text/javascript">
      window.onbeforeunload = function() {alert('unloadevent in main window');};
    </script>
    <iframe id="tpa" src="..test2.html"></iframe>
  </body>
</html>

test2.html:

<html>
  <body>
    <script type="text/javascript">
      self.onbeforeunload = function() {alert('unloadevent in frame window');};
    </script>
    <a href="http://www.google.com/">Link to for instance google</a>
  </body>
</html>
