Quite often it happens to me that I suggest an edit which adresses several issues with the post, improve them and have a suggested edit hanging in the review queue. While this edit is being reviewed (and usually being approved), others with edit priviledges are making the same / very similar improvements and my suggestion gets auto rejected by this community guy :)
While I do not have any issue with my posts being reviewed, it feels like a shame that the whole work is being done several times when somebody else is doing the same fix.
One example happened a few minutes ago. I suggested this edit to this post, and while this was hanging in the review queue for about 15 minutes, a very similar edit was done overwriting the suggested edit.
I understand that for edits around the same time those clashes can occur and work will be wasted, but why is there no mechanism which indicates that there is a pending edit which could be approved, modified, rejected by the 2k+ user who wants to edit that question or answer?
