/**
 * @fileoverview 'settings-multidevice-wifi-sync-item' encapsulates special
 * logic for the wifi sync item used in the multidevice subpage.
 *
 * Wifi sync depends on Chrome Sync being activated. This component uses sync
 * proxies from the people page to check whether chrome sync is enabled.
 *
 * If it is enabled the multidevice feature item is used in the standard way,
 * otherwise the feature-controller and localized-link slots are overridden with
 * a disabled toggle and the wifi sync localized string component that is a
 * special case containing two links.
