Which version supports rollback for bulk copy and is compatible with MySQL?

【TiDB Environment】Testing
【TiDB Version】5.7.25-TiDB-v7.1.1
【Reproduction Path】Start a transaction, insert data into table A using INSERT, and then use Bulk Copy to insert data into table B. Without committing the transaction, start another transaction to query both table A and table B.
【Encountered Issue】In the uncommitted state, it was found that data was already written into tables A and B. The transaction using ROLLBACK failed to roll back the changes. Manually deleting the large amount of data would be time-consuming. It is desired to improve the compatibility of Bulk Copy to support rollback functionality.
Which version of bulk copy can be rolled back in the future?
