[jotai/query] atomWithQuery gets stuck in react strict mode

If <React.StrictMode> is enabled then the query is stuck showing placeholder data.

Also, in bigger application I have this problem even without placeholderData - there the query is forever stuck in loading state with no observers attached. Seems to happen when there are many derived atoms. Hopefully it's the same root cause since I haven't been able to create smaller test case without placeholderData.

Thanks for reporting. Seems like a bug. We have struggled with StrictMode and something might still be missing.
Actually, we have one test failing with StrictMode.
#1417 may or may not be related.

Can you or anyone create a test case from the codesandbox, and then possibly try to fix it (though, it requires deeper understanding of the current implementation.)

I wanted to debug it in context of my project but unfortunately I was unable to make it work.
I've checked out jotai and replaced dependency with workspace however it fails to resolve type.
Unfortunately I have no experience using workspaces and no other idea how to do it.

#1435 would probably fix it, if it's done.
currently, it seems to work: https://codesandbox.io/s/jotai-query-stuck-in-strict-forked-qr2fzs

Thanks, it seems to also work with my full project. Requests are cancelled as before due to unmount but then retried on mount.
