I saw this "thing" in the sunglass holder. What is it? It looks to me like an LED mounted on a stalk.
It's the spring that puts tension on the latch. That square area below the latch mechanism (slightly above and left of your circle) presses against it.
Showed the picture to a friend of mine. It's a pressure stop or buffer designed to keep the door from rattling. It also provides a firm feel when you press on the door to open it.
