If QuickTime(wasn't QuickTime SDK) didn't installed, |MediaPlayer::isAvailable()| in |audioConstructor| return false then HTMLUnknownElement was created to insteated of HTMLAudioElement.
|isHTMLAudioElement(node)| in |isReachableFromDOM| just check whether element has "audio" tag name, |toHTMLAudioElement(node)| cast HTMLUnknownElement to HTMLAudioElement illegally then call |paused()|.
