slideToggle() behavior change between 1.3.2 and 1.2.6


I've posted this a few days ago in the general discussion group and
got no response. Maybe here is the better place.
Whereas jQuery1.2.6 showed the expected behavior, something changed in
version 1.3.2. Under certain circumstances, when the target element
is toggled into the hidden state, it automatically reappears. I
believe that it only occurs, if there are only floating elements in
the target. I narrowed it down to the following example:
<html>
<head>
<script type="text/javascript" src="jquery-1.3.2.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(".collapseme").show()
$(".clickme").click(function() {
$("body").find(".collapseme").slideToggle();
});
});
</script>
</head>
<body>
<div class="clickme">Click Me</div>
<div class="collapseme"><div style="float: left">Lorem ipsum dolor sit
amet, ....</div></div>
</body>
</html>
Is this a bug? Is this known?
