I am feeling increasingly iffy about where the line should be drawn with regard to certain edits on formatting.
For example, this edit struck me as sensible because the editor @Maryam highlighted the words in question for the OP and italicized book titles, which I thought would help the readability of the post. I especially appreciate book/film/article/magazine titles in italics, because they are eye candies in blocks of text. However, that edit was rejected by @ColleenV. I take it moderators' reviews are definitive, so there is no third opinion. I thought I'd come here and ask, along with several other reviews I am not so sure about.
Make no mistake, I have rejected other format edits that I consider inessential, e.g. this edit from the same editor. I thought they changed the grammar and style of the OP in this edit, thus making it difficult for answers to assess the OP's English proficiency. Unfortunately, the other two reviewers disagreed with me.
Another example is this edit. I also held a minority view that the edit was inessential in reformatting. The original post, though arguably taking up too much space, doesn't affect reading. I prefers quotes in blockquote.
