# When changing to single primary mode with no appointed primary,
# if a solo member exists with running slave channels, that
# member shall be the elected primary.
#
# Test:
# 0. This test needs three servers
# 1. server1 start group replication and server2 join
# 2. server1 as slave connection to server3
# 3. Set primary election max weight on server2
# 4. Execute action to single primary mode.
# It shall succeed, server 1 is the only with slave connections
# 5. Confirm that server2 has super_read_only= 1
# 6. Server1 is the primary server on the group
# Servers with slave channels take priority over high weight members
# 7. Cleanup
