MacOS GameKit Dashboard Doesn't Support Gamepad

We're working on a game for iOS, tvOS, and macOS that includes GameKit/GameCenter integration. On tvOS and iOS, when we bring up the Dashboard to access GameCenter with a Gamepad, the controller continues to function properly in that Dashboard. When we do so on macOS, the controller input continues through to the game and the GameCenter Dashboard needs to be interacted with using a mouse.

We're able to disable the input falling-through to our game but not being able to use the Dashboard with a controller is an inconsistent experience.

Is there a way to fix this? Is this a bug in macOS? All three platforms are using the same exact GKAccessPoint and GKViewController code.
