In this question I proposed an edit, then found I had made a typo (wanted sustituted, got dybstituted). Can't correct because I am stuck in peer review, and if I have to re-edit I am back in peer review. What can I do?
Unfortunately, there was nothing you could do. Once an edit is pending review, it is stuck there. (And if a reviewer misclicks — I’ve had that; I wanted to click Reject & edit and hit Reject instead — they’re stuck there, too.)
If you check out the help centre, there is nothing explicit on the subject. However, there is the sentence:
Edits are expected to be substantial and to leave the post better than you found it.
If you want to, you can read this as ‘pay attention to what you edit, so that you don’t introduce any errors in the process.’
Then again, that is what the Accept & edit function in the review queue is for. Reviewers should be looking out for what the edit suggestor changed and whether it introduced errors. Unfortunately, this process could have been improved in the case of this edit of your’s.
