Routine dependencies returns column name from a join <using> clause

Which version of common_schema are you using? (specify
revision+distribution)
2.2.11
revision 523

Which component is failing? (specify the view, function, etc.)
get_routine_dependencies

What is the expected output? What do you see instead?
A select statement that uses the USING clause in a join expression causes the 
get_routine_dependencies to return the column name instead of the table name.
This is the result from testproc().

+-------------+-------------+-------------+--------+
| schema_name | object_name | object_type | action |
+-------------+-------------+-------------+--------+
| myschema    | col2        | table       | select |
| myschema    | tableA      | table       | select |
+-------------+-------------+-------------+--------+

Can you provide with sample data?
create procedure testproc()
begin
  select *
  from tableA
  join tableB using (col1, col2);
end //

(As of version 1.1), please provide output of
SELECT * FROM common_schema.status
