<p>Tests that we don't garbage collect playing audio object or event listener.</p>
<p>According to http://www.whatwg.org/specs/web-apps/current-work/multipage/the-video-element.html,<br />
"4.8.10.8 Playing the media resource",<br />
"Media elements must not stop playing just because all references to them have
been removed; only once a media element is in a state where no further audio
could ever be played by that element may the element be garbage collected."<br /><br />
(see https://bugs.webkit.org/show_bug.cgi?id=66878, https://bugs.webkit.org/show_bug.cgi?id=70421, and http://crbug.com/62604 for more details).</p>
