I am not sure from the description. To be sure level=TRACE logging and
check the logfile.

But I think the reason is that NetworkManager doesn't want to write an
empty /etc/resolv.conf file. If Networkmanager has no nameservers, it
doesn't seem very useful to enforce that /etc/resolv.conf is empty.

Either, /etc/resolv.conf is already empty, then there is no effect.

Or, /etc/resolv.conf happens to contain correct name servers, then
clearing the file only breaks something that otherwise would work.

Or, /etc/resolv.conf contains invalid nameservers. But writing no
nameservers also isn't going to make it work.
