What happened?

Hello!

I use Cesium version 1.127.0. When a primitive has a heightReference other than NONE, its position on map is wrong in 2D mode. In 3D or without the heightReference, the primitive is placed properly.

If the primitive is displayed at lattitude longitude [0, 0], it is correctly placed.

Thank you for your help!

Sandcastle with option to add a point with a heightReference set to CLAMP_TO_GROUND

Reproduction steps

  1. Add two primitives (point or billboard) with and without a heightReference different than NONE
  2. Set the map in 2D mode
  3. The two primitives are not placed at the same position on map
