Views with CTEs parsed incorrectly

Comienza con el script test.php enlazado y reproduce la salida usando phpmyadmin/sql-parser 5.11.1. Traza cómo se analizan varias sentencias CREATE VIEW que contienen CTEs; después, añade cobertura para la forma sin paréntesis y verifica que cada vista siga siendo independiente y correcta sin requerir paréntesis.

Hi, parser has been working great for the most part but I ran into an issue today where I have multiple views with CTEs that get mixed together by the parser. I found that if I put parentheses around each view body definition the issue goes away, but MySQL does not require this.

Here is a minimal test script that demonstrates the issue:
test.php

Output from the test script on my machine follows. I am using phpmyadmin/sql-parser version 5.11.1 installed via composer.

-- SQL A:
CREATE VIEW view1 AS
WITH foo AS (SELECT abc FROM foo_table),
bar AS (SELECT id, xyz FROM bar_table)
SELECT foo.id AS id, foo.abc AS abc, bar.xyz AS xyz
FROM foo LEFT JOIN bar USING (id)
ORDER BY foo.abc, bar.xyz;

CREATE VIEW view2 AS
WITH foo AS (SELECT id, abc FROM foo_table),
bar AS (SELECT id, xyz FROM bar_table)
SELECT foo.id AS id, foo.abc AS abc, bar.xyz AS xyz
FROM foo LEFT JOIN bar USING (id)
ORDER BY foo.abc, bar.xyz;

-- Result A:
-- create VIEW view1
