This regressed in 0300b44d23b149a0b93dd0aa2e77d20a02882ddf. Specifically, the sliders and the stick/IR widgets did not update, but the spin boxes did update.
Will manually controlling both an accelerometer and a gyroscope at the
same time be reasonable to do? No idea. Was this easy to implement
thanks to the input override system? Yes.
