Is Cesium working for KML relative to ground attribute?

I am working on a project that has some KML files loaded into Cesium. However, when i added the terrain layer to my viewer, the loaded KML objects are not on their places supposed to be. I changed the altitudeMode from "relative to ground" to absolute and it still doesn't work that way.
Is Cesium KML good to work with terrain right now?


We haven’t implemented the “on terrain” features at the entity level yet, so that feature isn’t available for KML yet. It’s something we would like to add, but we need to implement polylines on terrain first.
