So, if the user cancels out of the spinner, they'll be left with sync
unsuppressed which means sync will automatically start with the default encrypt
settings the next time the user restarts.

I wonder if we need to add handling for cancelling the spinner to re-suppress
sync if sync hasn't started up?

Let's suppress in PSS::DisableForUser() as discussed.
