It seems like my earlier
proposed solution would be most useful. Reasoning: If the edit was rejected there's no 'edit credit' and no bump. If it was closed and the OP edited, and it wasn't reopened, it would remain closed (though the OP does get an 'edit credit', even a Badge if they don't already have one). So why give a bumper a credit if it remains closed - tag fixing is arguably better but minor edits that remain
