Fail to parse WITH query if it contains WINDOW

If a query contains the WINDOW clause parser fails with the following error:

self = <sql_metadata.parser.Parser object at 0x101e62990>

Query example:

WITH cte_1 AS (
    SELECT
        column_1
     FROM
         table_1
     WINDOW window_1 AS (
         PARTITION BY column_2
     )
)
SELECT
    column_1
FROM
    cte_1 AS alias_1
