Docker App Causing mDNSresponder to run on port 53

[cstetson]

Description

When I run Docker Desktop mDNSresponder takes over port 53 tcp/udp.

After Launching Docker Desktop

1|cstetson > sudo lsof -i :53
COMMAND   PID           USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
mDNSRespo 480 _mdnsresponder   29u  IPv4 0x3476ace87252be0d      0t0  UDP *:domain
mDNSRespo 480 _mdnsresponder   86u  IPv6 0x3476ace87252c60d      0t0  UDP *:domain
mDNSRespo 480 _mdnsresponder   91u  IPv4 0x3476aced4abdf31d      0t0  TCP *:domain (LISTEN)
mDNSRespo 480 _mdnsresponder   92u  IPv6 0x3476aced3816014d      0t0  TCP *:domain (LISTEN)

After quitting:

2|cstetson > sudo lsof -i :53
3|cstetson >

This seems to have started with 4.22.0

Given the history, this looks like it might be a regression as well.

Reproduce

1. Load Docker.app
2. sudo lsof -i :53
3. Quit Docker.app
4. sudo lsof -i :53

Expected behavior

mDNSresponder should not load on port 53 tcp/udp
