title: Does body.onload wait for IFrames?
body: <p>I know that <code>onload</code> event waits for page resources to load before firing - images, stylesheets, etc.</p>
  
  <p>But does this include IFrames inside the page? In other words, is it guaranteed that all the child Frames' <code>onload</code>s will always fire before the parent's does?</p>
  
  <p>Also, please let me know if behavior varies between browsers.</p>
