mount_point not removed on outgoing messages (version 2)

[alflexRH]

Version: current 2.0.11 from docker

mosquitto.conf:
per_listener_settings true

listener 1883
protocol mqtt
allow_anonymous true

listener 1884
protocol mqtt
mount_point foo/
allow_anonymous true

Client A: mosquitto_sub -t '#' -p 1883 -v
Client B: mosquitto_sub -t '#' -p 1884 -v

With mosquitto 2.0.11:
When sending with mosquitto_pub -t 'bas' -m 'hi' -p 1884:
Client A: foo/bas hi -- As expected. The mount_point foo/ is prepended to 'bas', and it arrives as coming from 'foo/bas'.
Client B: foo/bas hi -- Not as expected. The mount_point foo/ should have been removed.

With mosquitto 1.6:
When sending with mosquitto_pub -t 'bas' -m 'hi' -p 1884:
Client A: foo/bas hi -- As expected. The mount_point foo/ is prepended to 'bas', and it arrives as coming from 'foo/bas'.
Client B: bas hi -- As expected. the mount_poiint foo/ is removed, and it arrives as coming from 'bas'

Can confirm, I see this same problem on my MQTT server.

Thank you, that is now fixed and will be part of 2.0.12 shortly. I've also improved the mount point test to cover this situation.
