title: iframe resizing with scrollheight in chrome/safari
body: <p>I'm trying to resize (make bigger or smaller) an iframe based on it's contents. After a click on each page a method is called which does the resizing.</p>
  
  <p>In Chrome I can make the iframe bigger, but not smaller. document.body.scrollHeight is always the biggest value. </p>
  
  <p>So if one big page sets #iframe.height = '620px', and someone clicks on a link to page with less content scrollHeight will remain at 620px instead of decreasing.</p>
  
  <p>What's the proper way of handling this in Chrome/Safari?</p>
