FTColumnFlow is not working if embedded media (audio tag, to be exact) are used

[r007]

This code is breaking my layout:

<p>Audio:</p>

<audio class="wp-audio-shortcode" id="audio-587-1" preload="none" style="width: 100%; visibility: hidden;" controls="controls"><source type="audio/mpeg" src="http://127.0.0.1/wordpress/wp-content/uploads/2012/07/originaldixielandjazzbandwithalbernard-stlouisblues.mp3?_=1"><a href="http://127.0.0.1/wordpress/wp-content/uploads/2012/07/originaldixielandjazzbandwithalbernard-stlouisblues.mp3">http://127.0.0.1/wordpress/wp-content/uploads/2012/07/originaldixielandjazzbandwithalbernard-stlouisblues.mp3</a></audio>

Output in web console window:

TypeError: element.getAttribute is not a function
