Update on vector column returns error but modifies the value, results in further ER_KEY_NOT_FOUND

CREATE TABLE t (a INT, v BLOB NOT NULL, VECTOR INDEX (v));

INSERT INTO t VALUES (1,VEC_FROMTEXT('[0]'));

--error ER_TRUNCATED_WRONG_VALUE_FOR_FIELD

UPDATE t SET v = VEC_FROMTEXT('[0,0]');

SELECT a, VEC_TOTEXT(v) FROM t;

UPDATE t SET a = 2;

# Cleanup

DROP TABLE t;

UPDATE t SET v = VEC_FROMTEXT('[0,0]');

ERROR 22007: Incorrect vector value: '...' for column `test`.`t`.`v` at row 1

SELECT a, VEC_TOTEXT(v) FROM t;

a	VEC_TOTEXT(v)

1	[0.000000,0.000000]

UPDATE t SET a = 2;
