#11392 made _input_block in each BetaRowsetReaders sharable. However, for some types (e.g. nested array with more than 1 depth), the _column_vector_batches in RowBlockV2 can be nested which means that there is a ColumnVectorBatch inside another ColumnVectorBatch. In this case, the data of inner ColumnVectorBatch
may be corrupted because the data of _input_block is copied shallowly to the _output_block.
