That definitely look bad. As you say, there can be multiple rows in the
table, but it should be the same order of magnitude as
@@slave_parallel_threads, not millions.

Do you have any errors in the error log about failure to delete rows?
Anything else special to your setup that might be causing this?
Can you share the contents of the mysql.gtid_slave_pos table when this
happens?

That bug is rather different - the row count in the table is not growing,
but number of unpurged rows is.
