Will

keyboard_contorller->GetContainerWindow()->Contains(window)

work?

keyboard_controller->GetContainerWindow() has side effects creating the keyboard
window if it does not already exist.

If that's the case, can you check this in RWC (say
RWC::IsVirtualkeyboardWindow(aura::Window*)) and check it in the loop above?
Currently, only RWC knows about the virtual keyboard container and it'd be
better to keep it that way.

Done.
