NetworkManager can write in /etc/resolv.conf but other applications can do it too like Dnsmasq itself, Dhcpcd, Dhclient and Resolvconf. If NetworkManager have some configured connexions it can write again in /etc/resolv.conf using a Dhcp client for example. The configuration of Dnsmasq can do so too. Most applications who touch /etc/resolv.conf can be configure to not write in.
I suppose that Dnsmasq have some public Dns servers in it's configuration to resolv domain names because, 127.0.0.1 resolv nothing unless it lead to Named and it's public Dns servers for the resolution.
You can have a more precise idea of what is running related to the domain names resolution with the command
| Code: | | ps aux | grep -i -e dh -e dns -e name -e net -e reso -e wpa |

the output:
| Code: |
root 2141 0.0 0.3 581780 13704 ? Ssl 10:00 0:04 /usr/sbin/NetworkManager --no-daemon
root 2203 0.0 0.1 36716 5700 ? Ss 10:00 0:01 /usr/sbin/wpa_supplicant -u
root 2244 0.0 0.2 16816 9736 ? S 10:00 0:00 /sbin/dhclient -d -q -sf /usr/libexec/nm-dhcp-helper -pf /run/dhclient-wlp4s0.pid -lf /var/lib/NetworkManager/dhclient-b3dbbb03-03f4-4cd8-a3b5-fd0ca87186e2-wlp4s0.lease -cf /var/lib/NetworkManager/dhclient-wlp4s0.conf wlp4s0

there is dhclient work with my NM, i try to uncomment below line in /etc/dhcp/dhclient.conf
| Code: | | prepend domain-name-servers 127.0.0.1; |
and then restart NM, exec cat /etc/resolv.conf got
| Code: | # Generated by NetworkManager
nameserver 127.0.0.1
nameserver 10.0.0.1 |
and dig www.gentoo.org show that dns server is 127.0.0.1, so it looks like work well, thanks for your reminder |
