Regression in f387d024fc75569d2a4a338bfda76cc2f328f627. Just like `OrderByList` the `ExpressionList` expression used to wrap `Window.partition_by` must implement `get_group_by_cols` to ensure the necessary grouping when mixing window expressions with aggregate annotations is performed against the partition members and not the partition expression itself. This is necessary because while `partition_by` is implemented as a source expression of `Window` it's actually a fragment of the WINDOW expression at the SQL level and thus it should result in a group by its members and not the sum of them. Thanks ElRoberto538 for the report. Backport of e76cc93b0168fa3abbafb9af1ab4535814b751f0 from main
