title: webkit stylewithcss contenteditable not working?
body: <p>I'm trying to use contenteditable and styleWithCss.</p>
  
  <p>It doesn't seem to work in webkit.</p>
  
  <p>Anytime I use do an execCommand, it generates a <code>&lt;b&gt;</code> rather than the span I expected.</p>
  
  <p>Here's a demo:
  <a href="http://jsbin.com/izomo/2/edit" rel="noreferrer">http://jsbin.com/izomo/2/edit</a></p>
  
  <p>Select part of the text, click the bold button, and see the html output.</p>
  
  <p>Is this a bug or am I doing something wrong.</p>
  
  <p>Thank you very much.</p>
