    EBookBackendSqliteDB: Cursor API enhancements.
    
    When using the RESET origin, guarantee that both current
    and previous cursor states are reset. Same goes for alphabetic
    indexes, ensure that both cursor states are set to the new
    alphabetic index pointer and not just one of them.
