GraphicsView Interaction Event must continue when outside

[Yannikk1996]

EndInteraction is called when leaving the GraphicsView. This prevents from using this feature to draw useful controls.
There is also an IsInsideBounds Indication which is quite nice but does not help.

Much better behaviour would be that there is no EndInteraction when leaving. So controlling the drawn control is still possible. And Using the IsInsideBounds Indication to cancel the event yourself when it is needed.
