I noticed that as well; as I recall, swapping the two didn’t seem to change anything. I might open a pr or issue about this to either fix this or at least get some clarification as to whether that was really intended. I got a bit side-tracked by the entire `AttributedType` shenanigans, so I forgot about this.
