title: iframe on the page bottom: avoid automatic scroll of the page
body: <p>I have an <code>iframe</code> from the middle to bottom on a page. When I load the page it scrolls to the bottom. I tried to <code>body onload window.scroll(0,0)</code> but it does an ugly effect because it first goes down and then immediately scrolls up.</p>
  
  <p>What's the cause of this automatic scroll to bottom with <code>iframe</code> on the page?</p>
