changefeed cannot replicate DMLs in BDR mode if the targeted table is dropped and then re-created in the upstream.

What did you do?

1. Create tables t1, t2, and t3 in the upstream and downstream.
2. Create a changefeed and enable BDR mode to sync data from the source to the target.
3. Insert data into t1, and the sync proceeds normally.
4. Drop table t2.
5. Continue inserting data into t1 and t3, and the sync proceeds normally (dropping t2 does not affect t1).
6. Drop table t1.
7. Create table t1.
8. Insert data into t1, but unable to sync properly.
9. Insert data into t3, and the sync proceeds normally (dropping t1 does not affect t3).
10. Pause and resume the changefeed to restore normal sync.

What did you expect to see?
