title: What are some reasons IE9 wouldn't render the css in an iFrame?
body: <p>I have a site with an iFrame in it, and the iFrame gets almost rendered correctly.  There's just one problem -- a couple of the stylesheets don't get applied!</p>
  
  <p>Confusingly, the stylesheets get applied when you go directly to the page, not in an iFrame.</p>
  
  <p>WTFIE9?</p>
