    embed: Unbreak re-activation before the inactivity timeout
    
    When we build the UI for the second time, we need to populate the
    ViewModels with the items already present in the DocumentManager. We
    lost this as a fall out from 4c7ffba09ac512c2814d4518cc2a63b61f942334
    
    We also need to remove the rowRefs on each item when clearing the
    application state. The rowRefs are used as markers to indicate if they
    are already part of a ViewModel. If we don't clear them, then the
    ViewModel's filtering mechanism will prevent the items from being
    re-added when the application is re-activated.
