title: Scrollmagic: Prevent scrolling of page while in scene
body: <p>I want to use scrollmagic for an effect on my page.
  My scrollscene is defined and works.
  Now i want the page to stop scroll while the scene is not finished.</p>
  
  <p>I tried to put my scene in a container with <code>overflow-y: scroll;</code> but this died't work on firefox well. (I had to click in that section so scroll it.)</p>
  
  <p>So is it possible to disable scrolling of the whole page while my Scene is not finished?</p>
