The "Start binlog_dump" message hasn't been updated to include the slave's requested GTID position:
2019-08-25 20:05:05 139836760311552 [Note] Start binlog_dump to slave_server(2), pos(, 4)
|
See here:

For diagnostic purposes, I think it would be helpful if the GTID position were included. For example, maybe the message could be updated to something like this:
2019-08-25 20:05:05 139836760311552 [Note] Start binlog_dump to slave_server(2), pos(, 4), using_gtid(1), gtid('1-1-201,2-2-100')

I do see that the GTID position is available in the connect_gtid_state variable:
