I am seeing a lot of strange behavior when applying formating to the text of items in lists.  If Ichange fonts or color of individual items in the list after saving I sometimes seem portions of the list (or sometimes the entire list) getting repeated.  Even if I re-edit the text and delete the repeated item(s), saving makes them reappear again.  This doesn't happen appear to happen near as much on your demo site so it may be deployment or implementation related. Any ideas?
