<p>As you said, there will be other reviewers which will end up approving the suggestion. If they do not, one can go over the tag wiki and edit it to fix the mistaken review.</p>

<p>Then, if you are still uncomfortable with the user who suggested the edit, it is possible to ping him/her on chat (or leave a comment) and explain.</p>

<p>But don't worry, because everybody makes mistakes once in awhile.</p>
