Steps to reproduce:

1. Start docker container for ros:foxy

   sudo docker run -it --rm --net=host --name=foxy_test ros:foxy

2. Install and run demo node

   apt update && apt install -y ros-foxy-demo-nodes-cpp && source /opt/ros/foxy/setup.bash && ros2 run demo_nodes_cpp talker

3. Put talker in background (Ctrl-Z + bg) and run ros2 node list

Expected output:

/talker

Actual output:

Note ros2 topic echo /rosout works as expected
