[jQuery] Show()/Hide() Bug?


Source HTML file:

$(document).ready(function(){
$('p').hide('fast', function() {$(this).show('fast')});
});
//-->
</script>
</head>
<body>

Test text


</body>
</html>
After loading in browser I see:
------------------------------------
<body style="position: static;">
<p style="display: block; opacity: 0.9999;">Test text
</body>
Is it bug? :)
