UNNEST using Array index wrongly using covering index

INSERT INTO default VALUES("k200",{"messages":[{"seqno":100,"id":"abc"}]});

CREATE INDEX ix200 ON default(ALL ARRAY v.seqno FOR v IN messages END);

SELECT v.seqno FROM default UNNEST default.messages AS v WHERE v.id = "abc" AND v.seqno > 1;

-- Above query returns 0 results instead of 1 and uses ix200 and should n't be using cover fetch the data.
