sql_error_log plugin logs errors caught by procedure handler

When having the sql-error-log plugin enabled, and running a simple procedure test fetching data from a cursor, the following is written to the sql error plugin log, even though a HANDLER for NOT FOUND exists to catch this error, so that it is never actually returned to the client at all:

Error 1329: No data - zero rows fetched, selected, or processed ....

Looks as if the plugin API event that the sql error log plugin hooks into fires before the procedures HANDLER even has a chance to actually act on the error ...

CREATE TABLE t1(i INT);

DELIMITER //

CREATE PROCEDURE p1()

BEGIN

  DECLARE done INT DEFAULT FALSE;

  DECLARE x INT;

  DECLARE cur1 CURSOR FOR SELECT i FROM t1;

  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;

  OPEN cur1;

  read_loop: LOOP

    FETCH cur1 INTO x;

    IF done THEN

      LEAVE read_loop;

    END IF;

  END LOOP;

  CLOSE cur1;

END; //

DELIMITER ;

CALL p1();
