Expected Behavior

Following query to work without any errors

SELECT pr.name as name, MAX(pr.age) as age, MAX(city) as city
FROM (
  SELECT CAST(pr AS ROW(name VARCHAR, age int)) as pr, city
  FROM(
    VALUES 
      (ROW('John Doe', 30), 'New York'),
      (ROW('Jane Doe', 25), 'Los Angeles')
  ) AS t(pr, city)
)
GROUP BY GROUPING SETS (pr.name)

Current Behavior

Following query works

SELECT pr.name as name, MAX(pr.age) as age, MAX(city) as city
FROM (
  SELECT CAST(pr AS ROW(name VARCHAR, age int)) as pr, city
  FROM(
    VALUES 
      (ROW('John Doe', 30), 'New York'),
      (ROW('Jane Doe', 25), 'Los Angeles')
  ) AS t(pr, city)
)
GROUP BY pr.name

However following query fails

SELECT pr.name as name, MAX(pr.age) as age, MAX(city) as city
FROM (
  SELECT CAST(pr AS ROW(name VARCHAR, age int)) as pr, city
  FROM(
    VALUES 
      (ROW('John Doe', 30), 'New York'),
      (ROW('Jane Doe', 25), 'Los Angeles')
  ) AS t(pr, city)
)
GROUP BY GROUPING SETS (pr.name)

Error

Error(type=USER_ERROR, name=INVALID_COLUMN_REFERENCE, message="line 11:26: GROUP BY expression must be a column reference: pr.name

Shouldn't both work?
