Moon renders behind Earth

I am working on an application that uses Cesium to display the Earth, moon, satellites, and similar.

Something we have noticed is that the moon always renders behind the Earth, even if it is supposed to be in front of it (due to it’s position compared to the Earth and the camera). Here a sample, that has the Earth, moon, and a polyline from the Earth to the moon:

Is there any way to change that behavior?

Thank you!
