One of those rejections was mine.
I rejected the edit since - like Unionhawk mentions in the comments - it didn't show up as a spoiler, but as a block quote, and nowhere in the post was mention of a quotation. That's why I added the comment that "that type of markdown ('<') is reserved for quotations" (obviously, it should have been "'>'"...).
Another part of the problem is that I didn't check the comments, which would have elucidated matters.
I beg your pardon for the conflicting signals.
