----------------------------------------

Since this has been cherry-picked into the release branch, can we mark this as resolved?

> The wrong cache key is being used as it has not been namespaced to the state key.
> This was previously being done within StateFetchingIterators but https://github.com/apache/beam/pull/17121 changed that to use a single shared key.
> The fix is to subcache the cache before passing it into StateFetchingIterators restoring the prior behavior.
