sample iframe (I think it's because the iframe isn't immediately closed): 

<iframe width="560" height="315" src="//www.youtube.com/embed/xHUQ5C_yMo4" 
frameborder="0" allowfullscreen></iframe>  <p>ss</p>

If you just add "iframe" to the tag whitelist, all you're whitelisting is

    <iframe></iframe>

If you want to be able to have attributes, you have to explicitly allow any 
combination you want (look at how it's done with images for an example).

Like every sanitizer should, this one disallows everything by default.
