New ready event fires early in iframe in IE

New ready event fires early in iframe in IE

I just noticed that the new ready event fails within iframes in IE. I've created a simple test case that alerts the value of document.body.
<a href="http://brandonaaron.net/jquery/tickets/iframe_ready/shell.html">
http://brandonaaron.net/jquery/tickets/iframe_ready/shell.html</a>  <-- alerts null (within iframe)
<a href="http://brandonaaron.net/jquery/tickets/iframe_ready/test.html">http://brandonaaron.net/jquery/tickets/iframe_ready/test.html
</a>  <-- alerts properly (not within iframe)
<a href="http://jquery.com">jquery.com</a> is down ... when it comes back up I'll be creating a ticket.
