Please confirm that this policy works with multiprofiles on: if I have multiple
profiles and switch back and forth, then the policy always applies using the

I think that's the case due to the call to SetVirtualKeyboardBehaviorFromPrefs()
from ChromeLauncherController::ActiveUserChanged() but just want to make sure.
