Research direction
Start with the linked JSFiddle and reproduce the sequence in 3D terrain mode: remove a layer and then its source immediately. Trace the terrain, layer, and source removal lifecycle to identify why the immediate operation reads from undefined; done means the sequence completes without an error, without requiring the idle workaround.
