title: Can overflow:hidden affect layout?
body: <p>There's no way for me to explain this except to refer to the following <a href="http://jsfiddle.net/4f2RT/1/" rel="noreferrer">example on JS Fiddle</a>- in it, the last BLUE box does not extend to 100% of the width as expected after I introduce an overflow:hidden attribute.  </p>
  
  <p>I was under the impression overflow:hidden would affect visibility aspects only, and not interfere with layout.  Can someone explain what is going on in this example?</p>
  
  <p><strong>EDIT:</strong> 
  This problem seems limited to webkit browsers (e.g. Chrome)</p>
