How to drag items off screen


So I am trying to plan my tasks and when I can drag them until I get to the edge of the screen and then it stops, I cant drag it further than that. So I need to manually set the start date to move it further which isn’t the most convenient. Is that expected behavior or how do I configure it to allow me to drag issues further?

Please use the way from this sample to repaint and recalculate scale range when user moves task close to the edge
