Websockets - bind address/host in listener doesn't work for websockets protocol

[dchabrzyk]

1. Tested on RaspberryPi, Mosquitto version 2.0.11

2. Application doesn't respect the bind address/host option for listener parameter when using websockets protocol. After changing protocol to MQTT everything works fine.

3. Tested configuration entry
   listener 9001 127.0.0.1
   protocol websockets

4. netstat output
   masta@rpi-masta:/etc/mosquitto $ sudo netstat -tulnp | grep mosquitto
   tcp 0 0 127.0.0.1:1883 0.0.0.0:* LISTEN 3583/mosquitto
   tcp6 0 0 :::9001 :::* LISTEN 3583/mosquitto

is that the whole configuration?

listener 9001 127.0.0.1
protocol websockets

running this tiny config in a container for 2.0.11 has the same issue. 2.0.12 does not.
not sure if this is a libwebsockets or mosquitto issue, but you could try go up a few mosquitto versions too.
