Sensor drawing questions on 2D Maps

Hello all,

I have two questions about drawing sensors.
1). When I draw a ConicSensor and switch to a 2D map, the lines of the intersections are thicker than when displayed on a 3D map.(Pic1.png)
Is this a Cesium specification?

2). In the 2D map, the display position of the sensor changes from the 3D map in the case of Web Mercator. In the default 2D map, the sensor is displayed in the same position as in the 3D map.
I would like to make sure that the display position does not change between 2D and 3D in the case of the Mercator.(Pic2.png)
