IGNORE NULLS breaks window function parsing

[yusufshalaby]

Minimal example with "IGNORE NULLS" included in the window function.

And here it is working without:

select
    last_value(a) ignore nulls over (
        partition by c
        order by d
        rows between unbounded preceding and unbounded following
    ) as a,
    last_value(b) ignore nulls over (
        partition by c
        order by d
        rows between unbounded preceding and unbounded following
    ) as b
from some_table
where a = 1

Modifying the sql to the following fixes the issue:

select
    last_value(a ignore nulls) over (
        partition by c
        order by d
        rows between unbounded preceding and unbounded following
    ) as a,
    last_value(b ignore nulls) over (
        partition by c
        order by d
        rows between unbounded preceding and unbounded following
    ) as b
from some_table
where a = 1
