While the ClipboardStub is part of the InputStub, and the EventInjector
implements it, I suggest we don't bother separating the two at this level, i.e.
just pass the InputStub here, as we did previously.

ClipboardStub is no longer part of InputStub. But if it's clearer, I could just
pass a HostEventStub here.
