title: jquery offset and fixed position bug
body: <p>I found out that <a href="http://api.jquery.com/offset/" rel="nofollow">.offset()</a> will be relative to the parent element if it has the CSS property <code>position:fixed;</code></p>
  
  <p>Here is a <a href="http://jsfiddle.net/b6aum/" rel="nofollow">demo</a></p>
  
  <p>But it should be relative to the document, right?</p>
