Pagination using useSuspenseQuery gets empty array instead of cached array when api response with empty array

[geniusgordon]

Issue Description

I am trying to do pagination with useSuspenseQuery and typePolicies.

I've made a reproduction in stackblitz to better describe the issue: https://stackblitz.com/~/github.com/geniusgordon/stackblitz-starters-8ms1yj
(The example is forked from #11315)

I copied the merge function from offsetLimitPagination so that I can add some console.log.

After clicking "fetch more" multiple times, incoming will be an empty array when there are no items left, and the data returned from useSuspenseQuery becomes an empty array instead of the cached array which is the value returned in the merge function.

I tried useQuery as well, and it works normally.

Hey @geniusgordon 👋

Thanks for the reproduction! I believe this is a similar issue as #11642. I'll keep this open so that I can test a fix against this reproduction as well. Appreciate the report!

I changed my mind, I'm going to track this over in #11642 since the reproduction here looks similar to the one in that issue. Watch that issue for updates on this bug. Thanks!
