Scheduling the entire API state change callback caused the scheduled hide to fire the first time the user attempted to display the account creation overlay after a logout, because the drawable wasn't present before that (so its scheduler wasn't running). It is not theoretically safe to run `Hide()` unscheduled at its present call site (as the value change callbacks are fired on the background API thread). This could also be fixed by setting `AlwaysPresent = true`, but that's a pretty ugly and unperformant change to make in general.
