A recent wbeditentity change made its response data match the normal entity serialization. To avoid breaking MediaInfo users when the statements key in the JSON changed from "claims" to "statements", we’re also temporarily adding the same data under "claims" again. According to the announcement, that can be removed “on or around March 3”, i.e. with the 1.36.0-wmf.33 train.
Suggested change: remove this block.
