title: iFrame content lost after blind Effect
body: <p>I have a iframe, inside a div which blinds and show a couple of tabs. The content of the iframe is set on runtime.</p>
  
  <p>Whenever I activate the <code>toggle('blind')</code> event, the content of the iframe is lost. I'm logging the content of the iframe.</p>
  
  <p>Seems this problem is only presented with <code>Blind</code>, <code>Scale</code> and <code>Fold</code>, while with <code>Transfer</code> there seems to be happening an exception not finding a top. Weird this is, I launch the event from console and works find (Transfer), but the click crashes.</p>

  <p>Using <code>fade</code> works just perfect and looks fine.</p>
