DocNotes: odd behavior after some add/edit cycles

Some odd behavior after playing some edit/add not cycles:

1. click edit on an existing note
2. click cancel for the edit
3. double click add note
4. click cancel for the add
5. click edit on the existing note again

Instead of opening the editor, the page is scrolled to the very beginning with and empty anchor in the URL, e.g. http://developer.qt.nokia.com/doc/qt-4.8/qlist.html#
