I have recently made an edit that probably was only rejected, because the reviewer was afraid to check if the added content was correct or not (not much was added, see https://math.stackexchange.com/review/suggested-edits/813430), combined with the fact that the post came from a high-rep user.
How do I assume that? Supposedly, my edit changed the intent of the post, which is a little far fetched when all the edit does apart from fixing typos, a minor error and changing one sentence to avoid repition of the word 'hence', is fill a small gap - in a post that is pretty detailed and very much written in a way not to leave gaps (I'm talking about a mathematical proof).
So, what I did was ask the author if he would include my rejected edit, using the comment. It might however be possible that he won't respond, since he hasn't been active for a year or so.
Hence, I'm wondering if the link to the suggested edit in the comment will be there as long as SE is up, or if it will be deleted some time soon, so that the information pertaining to the edit remains available at least somewhere.
