> The producer hits timeouts which cause it to abort an active transaction.
> After aborting, the producer bumps its epoch, which transitions it back to
> the `READY` state. Following this, there are two errors for inflight
> requests, which cause an illegal state transition to `ABORTABLE_ERROR`. But
> how could the transaction ABORT complete if there were still inflight
> requests?
