Substitutions not expanding in arguments to Node

[dg-huawei]

This may just be user error, but I don't seem to be able to use substitutions in the 'arguments' field of the Node action. This is what I was trying (which didn't work):

service_bridge = Node(
    package="ros_gz_bridge",
    executable="parameter_bridge",
    arguments=[PathJoinSubstitution(["/world/", LaunchConfiguration("world"), "/control@ros_gz_interfaces/srv/ControlWorld"])],
    parameters=[
        {
            'use_sim_time': True,                
        }
    ],
)

Mean while hard-coding the path works fine:

service_bridge = Node(
    package="ros_gz_bridge",
    executable="parameter_bridge",
    arguments=["/world/store/control@ros_gz_interfaces/srv/ControlWorld"],
    parameters=[
        {
            'use_sim_time': True,                
        }
    ],
)

as does using an opaque function to do the substitution manually in python:

def opaque_function(context):
    
    world = LaunchConfiguration("world").perform(context)
    service_bridge = Node(
        package="ros_gz_bridge",
        executable="parameter_bridge",
        arguments=["/world/" + world + "/control@ros_gz_interfaces/srv/ControlWorld"],
        parameters=[
            {
                'use_sim_time': True,                
            }
        ],
    )
    
    return [service_bridge]

opaque_nodes = [OpaqueFunction(function=opaque_function)]

The documentation seems to suggest that a list of iterables or substitutions should be supported so I would expect this to work.
