> In the flow reducer we should be verifying that the incoming revision is
> newer than what is already saved. These scenarios can occur when polling
> takes longer when some other action. For slow connections this happens ofter
> as the size of the canvas payload increases.
> We also need to handle corner cases when the component as been deleted [1]
> and when a node's cluster connection state changes [2].
