Generally, I do very careful when placing down/up votes on a POST. If I misplace down/up votes on posts, I can't retract my vote once grace period ends.
This happens in this case also: Edit in grace period should allow un-downvote, too
In such cases, Can I do non-edits (as my Edits to any question or answer are applied immediately) on posts to retract my votes?
Is it valid behaviour?
