title: Mediaelement volume control is invisible on IE8
body: <p>When using mediaelement.js on <a href="http://hanselminutes.com" rel="noreferrer">http://hanselminutes.com</a>, the volume button is invisible on IE8. It seems that perhaps it's being covered up by the other audio controls being too wide? Oddly, if you click in the area that it should be, it's kind of there, although too far left. The volume icon never shows up.</p>
