Control + Left + Click does not work for inline functions/procs (4333864)

To reproduce the issue follow the steps below:

1. Create the package below:

CREATE OR REPLACE PACKAGE pkg1
AS
   FUNCTION func1(x varchar2 )
      RETURN NUMBER;

   PROCEDURE test_proc(y varchar2);
END pkg1;
/

CREATE OR REPLACE PACKAGE BODY pkg1
AS
   FUNCTION func1(x VARCHAR2)
      RETURN NUMBER
   IS
   BEGIN
      DBMS_OUTPUT.put_line('func1');
      RETURN 1;
   END func1;

   PROCEDURE test_proc(y VARCHAR2)
   IS
      i   NUMBER;

      FUNCTION inl_func(x VARCHAR2)
         RETURN NUMBER
      IS
      BEGIN
         DBMS_OUTPUT.put_line('inl_func');
         RETURN 1;
      END inl_func;
   BEGIN
      DBMS_OUTPUT.put_line('test_proc');
      i := func1('x');
      i := inl_func('x');
   END test_proc;
END pkg1;
/

2. Hover over func1 in line 22, (double) left-click -> cursor jumps to func1: ok
3. Hover over inl_func in line 23, (double) left-click -> cursor stays where it is: not ok
