Review Comment:
> Did you mean filtering out?
Well, we _want_ the attributes on `oneSideInputAttributes`, so it's not
filtering out, it's filtering for. If you look at the new `.filter` condition,
we are doing `oneSideInputAttributeSet.contains(a)`, so we only get back the
attributes that are in `oneSideInputAttributes`.
