ORACLE PL/SQL ROWTYPE code completion

When a function that returns a table rowtype is inside a PL/SQL block, Data Grip code completion works fine and suggest all table columns

The problem is when a function is created as store function or within a package, Data Grip code completion doesn't work and highlight code as an error.

CREATE TABLE employees (
    empno NUMBER,
    name  VARCHAR2(50) NOT NULL,
    job   VARCHAR2(50) NOT NULL,
    CONSTRAINT pk_employees PRIMARY KEY (empno)
);


INSERT INTO employees (empno, name, job)
VALUES (1, 'Steven Feuerstein', 'Oracle Developer Advocate');

INSERT INTO employees (empno, name, job)
VALUES (2, 'Tom Kyte', 'Senior Technical Architect');


CREATE PACKAGE pkg_employee AS
    FUNCTION one_row(p_emno employees.empno%TYPE) RETURN employees%ROWTYPE;
