title: Safari Mobile iframe with inner iframe size problems
body: <p>I have a "simple" web application that has a navigation and a content area. 
  Within the content area I have a iframe with more complex content. Unfortunately the content in the iframe has another iframe. </p>
  
  <p>The get an overview look here: </p>

  <p>In my scenario it is quite helpful to see the full iframe content, so we hide the navigation and change the content size on top of it: </p>

  <p>If I go back now to initial view the iframe inside the iframe doesn't change the size: </p>

  <p>This happend only on Safari mobile (iPad) OS 5.1. On normal Safari browser it works as expected. 
  Does anyone have a similar problem or an idea what is happening here? </p>
  
  <p>Of course a solution would be even better :)  </p>
