Is there an editing ‘grace period’ on answers after they have been posted?
It looks like if I post an answer, then revise it quickly say within 10 seconds, the original revision is "lost", and you can't rollback to it, or view it, and it doesn't even say that the answer has been edited.
This is fine most of the time, but there has been instances where someone revised my answer as I later quickly posted my own revision, and the other person's revision is lost. I won't know if there was any typo that was corrected, etc. Worse still, the person later may think that his/her corrections (if there were any) were unappreciated, since the errors may reappear in my latest revision (I'm no native English speaker).
Is this a real issue or am I just missing something?
