Along with the bug fix we need to ensure that the new way of grouping tools is properly documented in the API reference and a unit test to ensure that long-term support.

               // Undocumented tool grouping
                tools: [
                  "bold",
		 ['insertUnorderedList', 'insertOrderedList', 'indent', 'outdent'],
                ]
