floating ip on inactive port not shown in Horizon UI floating ip details

[Vincent Gerris]

When setting up a port that is not bound and assinging a Floating IP (FIP) to it, the FIP gets associated but the Horizon UI does not show the IP of the port, instead it shows a - .

The terraform/tofu snippet for the setup:

resource "openstack_networking_floatingip_associate_v2" "fip_1" {
                  floating_ip = data.openstack_networking_floatingip_v2.fip_1.address
                  port_id = openstack_networking_port_v2.port_vip.id
                }
resource "openstack_networking_port_v2" "port_vip" {
                  name = "port_vip"
                  network_id = data.openstack_networking_network_v2.network_1.id
                  fixed_ip {
                    subnet_id = data.openstack_networking_subnet_v2.subnet_1.id
                    ip_address = "192.168.56.30"
                  }
                }

Example from UI :

 185.102.215.242 floatit stack1-config-barssl-3-hostany-bootstrap-1896c992-3e17-4fab-b084-bb642c517cbe 192.168.56.20 europe-se-1-1a-net0 Active
 193.93.250.171 - europe-se-1-1a-net0 Active

The top one is a port that is asigned to a host that looks as expected, the second is not and corresponds to the terraform snippet. ( it is being used as a floating IP internal for load balancing )

Expected is to see the IP 192.168.56.30 that is set at creation.
