Why is Element.prototype undefined?
<p>Surprisingly, <a href="http://store.apple.com/us/browse/home/shop_ipad/family/ipad/select" rel="nofollow">this Apple page</a> has <code>Element.prototype</code> equal to <code>undefined</code>, so I cannot use this <a href="http://stackoverflow.com/questions/7754469/export-styling-of-html-elements">awesome snippet of code</a>.</p>

<p>Are there any reason for doing this?</p>
