> Consider the following tree:
> {code}
> LogicalAggregate[groupSet=$1, ...]
>   LogicalUnion
>     Input
> {code}
> When the rule is applied, the top-level Aggregate receives the same group set as the original Aggregate, which is wrong because it points to an incorrect attribute.
> {code}
> LogicalAggregate[groupSet=$1, ...] // <- wrong
>   LogicalUnion
>     LogicalAggregate[groupSet=$1, ...]
>       Input
> {code}
> The correct plan should be:
> {code}
> LogicalAggregate[groupSet=$0, ...]
>   LogicalUnion
>     LogicalAggregate[groupSet=$1, ...]
>       Input
> {code}
