inconsistency in creating Entities in Baking between Open and Closed Subscenes. | Official Unity Discord | Page 1

I am creating entities inside a BakingSystem without "attaching" them to a GameObject by adding a SceneSection component to them like this:

[WorldSystemFilter(WorldSystemFilterFlags.BakingSystem)]
    public partial class SystemSettingsBakingSys : SystemBase
    {
        private EntityQuery aiQuery;
        private EntityQuery settingsQuery;

        protected override void OnCreate()
        {
            aiQuery = new EntityQueryBuilder(WorldUpdateAllocator)
                .WithAll<DecisionRequest>()
                .WithAll<SceneSection>()
                .Build(this);
        }

        protected override void OnUpdate()
        {
            if (!aiQuery.IsEmpty)
            {
                var anyAIEntity = aiQuery.ToEntityArray(WorldUpdateAllocator)[0];
                var anySceneSectionComp = EntityManager.GetSharedComponent<SceneSection>(anyAIEntity);
                var anySceneGUID = anySceneSectionComp.SceneGUID;
                
                var assets = AssetDatabaseUtility.GetAllAssetsOfType<ConsiderationScrObj>();
                for (int i = 0; i < assets.Count; i++)
                {
                    var settingsEntity = this.EntityManager.CreateEntity();
                    EntityManager.AddSharedComponent(settingsEntity,new SceneSection
                    {
                        SceneGUID = anySceneGUID,
                        Section = 0
                    });
                }
            }
        }
    }

when the subscene is closed everything works as expected. those entities are created and serialized in the subscene.

when the subscene is open the entities dont exist. but the System did run.

does the open subscene rely on entities to be attached to gameobjects to keep them alive? why is this behaviour different for closed subscenes.
