Based on past experience of some of my earliest rejected edits (1 and 2), I would have thought that this suggested edit should have been rejected.
Adding information from the comments (made by the OP) to the original question is an accepted practice, I believe. However, adding third-party experience is usually frowned upon. As an example, in my first two cases, I wasn't changing the authors intent but either, in the case of the first rejected edit, a link to the library's update notes or, in the case of the second rejected edit, adding a product link. Both of which were factual, un-deniably related, information and/or links - whereas this recently accepted suggested edit seems to be more of a supposition.
So, is it acceptable to edit in one's own (possibly relevant) experiences to another user's post?
Sorry, after re-reading, this does seem to read like I am moaning about a couple of my ancient rejected edits... just to clarify, that is not so. It's about the recent edit (which was quickly fixed, and I hadn't realised - therefore this entire post is superfluous to requirements.)
