> 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.
