# Edit rejected because nearly-identical, later edit was done. Why?

I've had this happen twice now. I suggested an answer edit to add the spoiler notation to an answer without it. I find later that my edit has been rejected because of a conflict with another edit, and in its place is an edit that was almost identical to mine.

My question is two-fold:

Why is my suggestion rejected and a later (similar) one implemented/approved?

Is this something that should happen on Puzzling.SE?

If I need to split this up into two questions, let me know.
