Pause interval refreshing when page is backgrounded

[camflan]

Is there a setting that will let us suspend interval updates once the page is backgrounded, and then resume when it's regained focus?

Just released version 0.3.20, in which queries will no longer automatically attempt to refetch in the background when using refetchInterval. If you want the query to refetch while in the background, there is now a query config option called refetchIntervalInBackground that you can set to true.
