I think there is a small UI bug, which seems to affect at least beta metas (likely beta mains, too, I don't know about graduated sites with their custom designs). When a deleted post is at the top of the page, the dark background of the deleted question extends into the pagination:
For those with enough rep on Code Golf (or SE staff), you can see it in action here.
Edit: Even for non-deleted questions it's a bit weird that the pagination is part of the answer's div. E.g. when you open a question with a link to the answer at the top of the page, and the answer is highlighted for a second, the highlighting also includes the pagination.
