useIsMutating and useMutationState always trigger rerenders

[mleister97]

Currently, the issue is that the two hooks, useIsMutating and useMutationState, always trigger a rerender, regardless of the specified mutationKey to filter. For instance, if I have a grid of 100x100, and each cell can have its own loading state, I would use a mutationKey like ['CELL', 3, 7] for mutations. Unfortunately, all cells now trigger a rerender. Do you have any solution for this?

You can also see this when justing using a key for the filter which does not even exist, e.g.

// this does still rerender, regardless of the filter mutationKey
const isMutatingPosts = useIsMutating({ mutationKey: ['MUTATION_KEY_DOES_NOT_EVEN_EXIST'] })

can you show a reproduction please because that should not be the case

Disregard that; I am unable to replicate the issue.

I will provide my 'reproducible' case as evidence that contradicts my previous statement: https://stackblitz.com/edit/tanstack-query-vba6tk?file=src%2Findex.jsx
