I fixed this for the XMLDocument case. e.g. when loading xml via ajax from server or when using jQuery.parseXML .

The use case as outlined in the report isn't supported at the moment. As you can't pass arbitrary xml string to $( html ). If that works is mainly browser dependent and fails in most versions of IE. Also the differences between the browsers probably derive from the fact that the DOM Level 1 method getElementsByTag handles namespaced tagnames differently across browsers. For further info check #7583 and #6491 or just search the bug tracker for namespace, xml related tickets.
