gathered an excellent comment by @Mackk, which included a link to a video. I thought that the video would enhance the answer greatly, so I submitted an edit to add the video into the answer. The edit, which credited @Mackk, was accepted.
I then flagged the comment as being obsolete, since the comment was now included in the answer. The flag was rejected. Since the video in the comment is now in the answer, and the answer credits Mackk, why was the flag rejected? Was it just an oversight by the mod, or a misunderstanding on my part?
