Got several warnings on <button ... > <div ... >, etc., such as: attribute 'data-dojo-type' is not a valid attribute of element 'button' attribute 'data-dojo-props' is not a valid attribute of element 'button' attribute 'data-dojo-type' is not a valid attribute of element 'div' attribute 'data-dojo-props' is not a valid attribute of element 'div' How can those problems be handled? Thanks.
