I attempt to run the following two lines of sample code in Sandcastle:

```
var viewer = new Cesium.Viewer('cesiumContainer');
viewer.scene.globe.enableLighting = true;

```

And when I change the scene mode to 2D and move the flat map, the lighting effect will alternate appearance and disappearance.

Is it normal or a bug? Thanks a lot~
