Found while trying to import an instanced point-instancer with the operator setting `support_scene_instancing=false`. The point-instancer Prototype would be partially processed but not completely since the option was disabled. This caused a discrepancy during the final portion of import where the view layer was synced and we attempted to query for an object that was not present.
