Using JSON_SET in the VIEW creation truncates the JSON data

CREATE VIEW v_bad AS

SELECT JSON_SET('{}', '$.k1', 'x', '$.k2', REPEAT('b', 40)) AS j;

CREATE VIEW v_good AS

SELECT JSON_SET('{}', '$.k2', REPEAT('b', 40), '$.k1', 'x') AS j;

SELECT 'bad_view' AS case_name, LENGTH(j) AS len, JSON_VALID(j) AS is_valid, j FROM v_bad; -- bad_view	33	0	{"k1": "x", "k2": "bbbbbbbbbbbbbb

SELECT 'good_view' AS case_name, LENGTH(j) AS len, JSON_VALID(j) AS is_valid, j FROM v_good; -- good_view	61	1	{"k2": "bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb", "k1": "x"}
