One could put into the markdown a comment indicating that the text was intentional.
Oh wait, we already did - remember that time we met, a few weeks ago,
over steak and drinks? That was a great stake.
<!-- That is supposed to be stake - not steak. I know. It's intentional. -->
We talked about cars. ...
This would then indicate both to someone going in and editing it along with anyone looking at the side by side markdown (how I normally view suggested edit reviews) that this was something that wasn't to be changed.
When looking at a suggested edit review I consider it 'stateless'. There's the old version - here's the new version. Is it an improvement? yes? Approved. I don't see the history (thats quite a bit of a hoop to jump through to view). I only see the text. Thus, any hints to editors or reviewers need to be in the markdown itself.
At that point, I would see that this is the state the author wanted and work from that. Without any other guidance in the text, I have to go on what I see.
