Store-only data like sidebar state updates immediately when changed because it exists only in the JavaScript application memory. Changes to this data automatically trigger component re-renders through the Redux subscription system.
Database-cached data doesn’t automatically update when the database changes externally. The WordPress editor store and database operate as separate systems without real-time synchronization mechanisms.
Page reloads fetch fresh database data into the store, updating blocks that display database content. Understanding this distinction helps set appropriate expectations for data freshness and user experience.
