Recently I stumbled upon an answer which had a small bug (incorrect variable name) pointed out in the comments. To achieve better reader experience, I edited this comment into the answer.
The OP of the answer rejected my edit claiming it was incorrect and subsequently made the exact same edit under their name. I understand they may have made a mistake when reviewing my proposal, but I believe they should have accepted my proposal instead of creating their own.
I'm not too worried about the situation, but misattributions such as this one result in no reputation gains for the editors, which is problematic especially for users with lower reputation trying to get privileges by meaningful activities.
I believe there should be a policy in place encouraging re-acceptance of rejected edits instead of submitting them again from a different account.
