I was trying to display an ellipse with editable radius on the map and I found a strange behavior when the radius is set to zero after being bigger. The ellipse keeps its last non zero radius and move around when I zoom or move around. I've attached a sample project to show that behavior. So just zoom one time so that the shape is displayed (I don't understand neither why this is necessary) and change the size of the ellipse to zero using the slider on the top. This behavior also happens when using MapPathView containing ArgSegments from and to the same position so I guess this may happens with all Map*View with dimensions set to zero.
Thank for taking a look,
