I often feel it is a waste of time when you are editing a question and shortly before you finish you see that the question already got edited, and your edit does not improve the corrections which were already made.
It would be nice if there is a "warning" that for the question there is already someone who takes care of it, or there is "editing in progress", so you might review it later.
Seems related to this: Editing long questions in stages
Which is 7 years old, and nothing changed. I do think that this is a problem (maybe minor), but a comfort change for users who take care of poorly written questions, is desireable in my opinion.
