title: Weird webkit issue with position: fixed
body: <p><a href="http://workshop.wpcoder.com/daniel/tvexperts/" rel="noreferrer">http://workshop.wpcoder.com/daniel/tvexperts/</a></p>
  
  <p>In Chrome, if you click "Production" and then "Contact" the position: fixed header disappears, but comes back when you move the scrollwheel. I have no idea what the cause is, and so far I can only detect it in Safari and Chrome, but Firefox is fine so I think it is a webkit bug.</p>
