Doesn't Differentiate Using Aliases in Group By

The test that I used was:

sql = """SELECT
    table_schema
    , CASE WHEN table_schema = 'my_table' THEN 1 ELSE 0 END as test
    , COUNT(*)

FROM information_schema.columns
GROUP BY
    table_schema
    , test
LIMIT 10 """
print(sqlglot.transpile(sql, read='postgres', write='oracle', identify=True, pretty=True)[0])

And what it returned was:

SELECT
  "table_schema",
  CASE
    WHEN "table_schema" = 'my_table'
    THEN 1
    ELSE 0
  END AS "test",
  COUNT(*)
FROM "information_schema"."columns"
GROUP BY
  "table_schema",
  "test"
LIMIT 10

Referencing aliases in the group by is not supported in Oracle SQL, so this returns an error
