Formatting error when SQL query includes GROUP clause (4279232)

When the following SELECT is entered into Toad For Oracle 12.10 returns an error even if the query is correct and returns the valid result:
SELECT *
FROM (SELECT 'A' x, '1' y FROM DUAL UNION
  SELECT 'A' x, '2' y FROM DUAL UNION
  SELECT 'B' x, '1' y FROM DUAL UNION
  SELECT 'B' x, '2' y FROM DUAL) PIVOT (LISTAGG (y, ',') within GROUP (ORDER BY y) for x in ('A' as A, 'B' as B))

The error is: [Error] Syntax check (10: 42):

WORKAROUND:
