Timeline External Drag-and-Drop Resource Scrolling

Mobiscroll 5.35.4 Timeline View. The timeline View has many resources and the user can manually scroll to see the ones further down the page. When dragging events already scheduled on the mobiscroll timeline view, the calendar automatically pages down to see additional resources as the dragged event approaches the bottom of the visible calendar. When dragging external events onto the calendar, the timeline view does NOT scroll down to see additional resources as a dragged event approaches the bottom of the calendar. Interestingly, the horizontal scroll to see dates further out in time works for both external events and already scheduled events.

Any suggestions how to fix the resource scrolling for externally dragged events?
