calling $(...).data() changes behaviour of $(...).data('nosuchkey')

If you call ...data('foo') you get a result of null, but if you then call ...data() followed by ...data('foo') the result is undefined:

<html>

<head>

$(document).ready(function() {

$("#firstvalue").html(typeof $("#foo").data('bar'));

var ignored = $("#foo").data();

$("#secondvalue").html(typeof $("#foo").data('bar'));

});

</script>

</head>

<body>

<div id="foo">Div named foo</div>

<div>First value of $("#foo").data('bar'):<span id="firstvalue"/></div>

<div>Second value of $("#foo").data('bar'):<span id="secondvalue"/></div>

</body>

</html>

I wasn't able to replicate this (namely the result of null) so I think this is fixed on our end. I added some extra tests:
