Set whether PolylineAnnotation holding this PolylineAnnotationGroupInteractionsState should be draggable, meaning it can be dragged across the screen when touched and moved. Note: If this param is used when PolylineAnnotation is also part of the cluster, then once PolylineAnnotation is dragged, it moves out of the cluster and can't be added back to it and is rendered as a separate PolylineAnnotation.
