Tooltip is not hidden by clicking a link

<link href="../css/ui-lightness/jquery-ui-1.10.3.custom.css" rel="stylesheet">

<script src="../js/jquery-1.9.1.js"></script>

<script src="../js/jquery-ui-1.10.3.custom.min.js"></script>

<script type="text/javascript">

$(function() {

$(document).tooltip();

});

</script>

I have "a href" links in the page where the above has been added. They have title attributes and their target is "_blank". The standard browser tootlip display mechanism hides the tooltip when you click a link. In IE 10, Windows 7, the UI tooltips remain visible after clicking the links: an external browser window opens, and when you close it and return to the original page, the tooltip is still visible. I wouldn't expect this to be the default behavior.

Thanks!
