Non-undefined placeholderData types as possibly undefined
placeholderData function always returns a proper result (not undefined), then why is the resulting data property typed as T | undefined?
Consider the following example:

I'm having an issue with an uncaught promise on a mutation
``TypeScript
const mutationAddQuestion = useMutation({
mutationFn: async (formData: FormData) => {
const correctAnswer = Array.from({ length: numberOfAnswers }).findIndex((_, index) => (formData.get(correctAnswer${index}`) === 'on')) + 1;...Drawbacks of multiple related mutations in one hook?
Is it possible to have mutation queue that will run until the queue empty ?

useSuspenseQuery when offline
experimental_createPersister so the network mode is set to offlineFirst. Whenever I render this when offline, and no data is persisted yet, the suspense fallback (LoadingComponent) keeps showing. Instead I want a placeholder to tell the user they are offline and they should retry when online.
```ts
<QueryErrorResetBoundary>...`keepPreviousData` with `useSuspenseQuery` with nextjs streaming ssr
useSuspenseQuery with ReactQueryStreamedHydration from @tanstack/react-query-next-experimental
This works great
However my query has a regular changing query key, but I want to show the previous data during loading states
So I switched useSuspenseQuery to useQuery with placeholderData: keepPreviousData, this also worked great however it lost all of the server streaming behavior...queryOptions counterpart for useMutation?
queryOptions as mentioned in this section of the documentation:
https://tanstack.com/query/v5/docs/framework/react/guides/query-options
I was wondering if there was a counterpart for this for useMutation....Query returning old data after mutation when manually setting data using setQueryData

UI gets stuck after updating React to React 18
Is there a way to either go back to initial state or set data directly?
How do I tell useQuery that initial data is prefetched on the server?
MyData | undefined because useQuery doesn't know the initial data will be there. How do I solve that? For now I solved it by setting initialData: {} as MyData in useQuery but I wonder if there is a better way?
