Would it be crazy to mock this and add a brief smoke test for
ObserveWheelEventAndResult? Might need to add a message loop to the test harness
to verify the async callback (not sure though).

This definitely needs to be done, but I want to clean up some other things first
(like, make the elasticity controller deterministic first).
