Editor does not split this package (Open file)

CREATE OR REPLACE PACKAGE pkg_tst
IS
TYPE numberarraytype IS TABLE OF NUMBER
INDEX BY PLS_INTEGER;

PROCEDURE prc_tst (p_arr IN numberarraytype DEFAULT CAST (NULL AS numberarraytype));

END;
/

CREATE OR REPLACE PACKAGE BODY pkg_tst
IS
PROCEDURE prc_tst (p_arr IN numberarraytype DEFAULT CAST (NULL AS numberarraytype))
IS
BEGIN
NULL;
END;
END;
/

But PL/SQL Developer splits…
