WAL senders sending logically-decoded data fail to properly report in "streaming" state when starting up, hence as long as one extra record is not replayed, such WAL senders would remain in a "catchup" state, which is inconsistent with the physical cousin. This can be easily reproduced by for example using pg_recvlogical and restarting the upstream server. The TAP tests have been slightly modified to detect the failure and strengthened so as future tests also make sure that a node is in streaming state when waiting for its catchup. Backpatch down to 9.4 where this code has been introduced.
