If I filter a jQuery object and use .prependTo() or .appendTo() to insert the elements into the document, the removed elements are still inserted into the document. See below for an example:

<script>

var

html = '<style type="text/css">body {color:red;}</style>' +

'<script>alert("foo")</script>' +

'<div id="foo">bar</div>',

$elems = $(html).filter('div');

$elems contains only the <div> element

$elems.prependTo(document.body);

the <style>, <script>, and <div> elements are all

inserted into the document's body.

only the <div> should be inserted.

</script>
