Paging wants to reset local Append/Prepend states while retaining previous Refresh state upon a new generation. Refresh state is retained to prevent loading animation from flickering,

i.e. we want to prevent this:

Refresh.Loading --> [new generation] --> Refresh.NotLoading --> Refresh.Loading

and want this:

Refresh.Loading --> [new generation] --> Refresh.Loading


To do that reset, Fetcher needs to keep track of multi-gen local LoadStates which it currently doesn't do so.

An idea is to have fetcher hoist the state up in a separate operator to inject the correct source state.
