Commit ce0fdbfe97 made tablesync slots permanent and allow Drop Subscription to drop such slots. However, it is possible that before tablesync worker could get the acknowledgment of slot creation, drop subscription stops it and that can lead to a dangling slot on the publisher. Prevent cancel/die interrupts while creating a slot in the tablesync worker.
