Sbould make sure that a page that goes into the page cache with an active scroll comes out of it without one, probably?

> Source/WebKit/Shared/RemoteLayerTree/RemoteScrollingUIState.h:50
> +    RemoteScrollingUIState() = default;

Isn't this line needless?

It is called back/forward cache now and is the same whether you proses-swap or not :)
