As per this url , in the first paragraph it says that "Resizing a task by dragging its start date is not allowed."
But in the ext js version which we are using currently using. We can drag the start of the task bar. And also in the https://bryntum.com/products/gantt/docs/api/SchedulerPro/feature/PercentBar we can drag the start of the task bar and resize it.
Whereas in examples https://www.bryntum.com/products/gantt/examples/, we cannot do that. I want to know if that feature is supported or not. If it is not supported why it was supported in ext js version and why it is not supported now. What can I do to enable it in the Gantt charts
