    # 108386: This fixes an issue where operation models could not be marshalled
    #  when there is an attached parent_op, as the parent_op may contain hashes
    #  with default procs which is not supported by `Marshal.dump`. This mixin
    #  therefore excludes this instance variable from being dumped and loaded.
