Fixed issue where the previous subscene compatibility fixes didn't work correctly with multiple subscenes having the same atom names, e.g. SubScene/InvisibleLight and SubScene#2/InvisibleLight. When in a SubScene, the plugin now correctly identifies the target atom that belongs to the same SubScene.
It might work incorrectly if the plugin targets an atom that is in a different SubScene than the plugin itself (or not part of a SubScene), but that's bad practice anyway - SubScenes are meant to be fully self-contained.
