> There's a bug in top.LargestPerKey that appears when running it on a runner
> that has combiner lifting. Since it's similar to a GBK, we should be
> inputting a K, V and receiving a K, []V as output. When the runner has
> combiner lifting, the []V always contains an empty slice.
>
> I already found the fix for this, just logging this to attach it to the PR.
