Issue with ORDER BY clause by original column name when GROUP BY used

[IMMSPgisgroup]

As I see in the browser version of AlaSQL 4.17.2:

alasql("SELECT num As position, letter As note FROM ? GROUP BY num, letter ORDER BY num", [[{"num": 100, "letter": "one"}, {"num": 50, "letter": "two"}, {"num": 10, "letter": "two"}]]);

or

alasql("SELECT num As position, letter As note FROM ? GROUP BY num, letter ORDER BY num ASC", [[{"num": 100, "letter": "one"}, {"num": 50, "letter": "two"}, {"num": 10, "letter": "two"}]]);

or

alasql("SELECT num As position, letter As note FROM ? GROUP BY num, letter ORDER BY num DESC", [[{"num": 100, "letter": "one"}, {"num": 50, "letter": "two"}, {"num": 10, "letter": "two"}]]);

position	note
100	one
50	two
10	two

In result I have non-sorted JSON-array.
Ordering by column doesn`t work in AlaSQL for this sample.

Is this wrong? Because in PostgreSQL 17, as I see:

SELECT num As position, letter As note FROM (VALUES (100, 'one'), (50, 'two'), (10, 'two')) As t (num, letter) GROUP BY num, letter ORDER BY num;

position	note
10	two
50	two
100	one

(3 rows)
