Lights not filtered by Layer

Have a scene with two sub-scenes rendered into texture render targets and then composed together. Let the scene contents be controlled by LayerFilters and Layers for each sub-scene. Have some lights in each sub-scene.

It seems that light sources are gathered irrespective of Layer components. This leads to weird results since unexpected lights (i.e. also the lights from the other sub-scene) get applied in each sub-scene.
