I'm trying to put and html5 audio tag in a content block (in a blog control) and it keeps striping out the word "controls" from the audio tag.
It works correctly in the MVC content block but not and of the webforms radEditors
<audio src="/june-6-2016---federal-tax-update.mp3" preload="auto" controls>
<p>Your browser does not support the <code>audio</code> element.</p>
Is there some setting I can change for the editor to all the word "controls" to be inside a tag?
