What steps will reproduce the problem?
(1) Policies on YAPS:
    DeviceShowUserNamesOnSignin=true
    DeviceLoginScreenInputMethods=xkb:us::eng,xkb:ch::ger
(2) Enroll device and sign in as user.
(3) Go to settings and add languages such as French, German and their associated keyboards.
(4) Exit settings and select FR keyboard from bottom right of screen. If FR is unavailable, sign-out, sign-in and try again.
(5) Sign-out. In the Sign-in screen, FR is current input method with the current user pod in focus.
(6) Click on "Add person". Since FR is only associated to the previous user session, it is expected the first mandated policy input method should be switched in i.e. US keyboard. However, FR remains as the input method in the Sign-in screen.


What is the expected result?

With reference to go/cros-locale-input-policy-dd:

1. When a user focuses their pod on the Sign-in screen, the user’s least-recently-used Input Method (LRU Input Method) will be loaded from the local state and switched to.

2. When a user pod loses focus on the Sign-in screen, the Input Method will switch back to the Input Method mandated by policy for the Sign-In screen.


What happens instead?

Without changing the input method manually, the user's least-recently-used Input Method stays as the current input method throughout the Sign-In screen whether the user pod is in focus or not.
