I prefer to see the comments of an issue in chronological order, so I have them sorted "Oldest first".
Up until a few days or a week ago, that meant that I first saw

and then the N newest comments (N = 5?) ordered from old to new. I had no problem with that.
Now suddenly I see the N oldest comments followed by a "View [M] remaining newer comments" button.
Is this change intentional? Can I do something to get back the previous behaviour?
