Tree Grid Pagination with Drag and Drop

I’m using TreeGrid with server side pagination.
I have an issue in Drag and drop function.

Scenario: In 1st page of grid end one parent row and in next page their child’s are there.
When I try to move/copy in 1st page of last parent by using drag and drop, only dragged parent placed. But when I drop, parent with their child’s want drop dynamically.

Is this possible ? Have any suggestion for in this case ?

Thank you !
