In dojo example here: https://dojo.telerik.com/UVuVAcoG The summary is shown as diamond just like milestone. However, in the example here: https://demos.telerik.com/kendo-ui/gantt/index if you move milestone task under any task which is not summary and has no other tasks as subtask, nothing is shown for summary task. We are having similar behaviour in our gantt. Why is the dojo example behaving different than the kendo example on the index page?
