Any way to disable background input within Dolphin?

[Koestu]

I don't know how far back this was added, but it's annoying right now because I have the Wiimote A and B buttons bound to left click and right click on the mouse, but navigating Dolphin's menu causes input in-game. Can I disable this behavior? I know there's background input for outside of Dolphin, but I prefer to only have control when the game window is in focus, not Dolphin in general.
