When picking a suggested duplicate with many answers, there is no separation between the answers in the duplicate selection dialog.
On the main site, where answers can be longer, this is even more confusing, since the score does not appear so close to the top, so it's even harder to say where one answer ends and another begins.

The problem is when there are many long answers, and you want to quickly scan through them and see if you can find some relevant keywords. Since the line stretches through the entire dialog, you can just scan the left and middle parts of the dialog.
Currently in order to find out when an answer ends and a new one begins you have to move your eyes constantly and look for the user symbol and whatnot. This means that the focus shifts all over the dialog, instead of being focused at one area, and that's tiresome and distracting.
So please bring back that separator line! It was helpful!
