Tab caption appears in multiple places but not as a true tab item
On upgrading to JQuery U 1.9.2 I am seeing some odd behaviour relating to adding tabs (see graphic below where "GSE-0002" should only be present in the top tab container. What's really is odd is "GSE-0002" also appears in the tab containers below the main tab although they are not displayed as standard tabs. I have replaced the "add" api call with the new recommendation:
// $(tabs).tabs('add', "Project.html", sPID);
$("<li><a href='Project.html'>" + sPID + "</a></li>").appendTo("#tabs .ui-tabs-nav");
Switching back to using "add" works perfectly as it did before. "#tabs" is unique and only exists as the top tab container.
Any ideas for this newbie?
