Refactor > Rename not working within parameters within procedure calls

DECLARE
v_test PLS_INTEGER;
BEGIN
v_test := 1; – works here
dbms_output.put_line( v_test );
END;

I can rename the variable when selecting one of the first two occurrences, but when selecting v_test within the procedure call, Refactor > Rename gives me the following warning:
dbms_output.put_line( v_test ); is not a locally defined identifier.

No big deal, but is this something that can be easily fixed? Thanks!

Fixed for next beta.
