Attempt fixing the traffic light position

- For macOS, we render the traffic lights at the top-left of windows in a custom way. But then, for whatever reason, production builds have a smaller traffic light. So we now take extra measures to position both the larger and smaller versions correctly. Very nitpicky but it did look very bad without this.
