Network Manager - dns search domains not taken into account

[Poil]

Hi,

In NetworkManager, I've set method to "automatic (DHCP) addresses only" and a DNS server to "127.0.0.1" and search domains to ".xxxxx,.team2.intra.xxxxx,.xxxxx.com"

But /etc/resolv.conf does not take the search domains into account
I've tried to reboot, to up/down the link via "nmcli c down" and the gui, to restart systemd-resolved ...

All was working fine before upgrading from 16.04 to 18.04
