BrowserWebDriverContainer#withNetworkMode does not seem to work

Hi,
I am starting a Docker-Compose with (in Kotlin):

 @ClassRule
 @JvmField
 val env: DockerComposeContainer =
                    DockerComposeContainer(composeId, File("../docker-compose.yml"))
                                                    .withLocalCompose(true)

this works just fine. However, I want to add a Chrome Docker image to control with TestContainer, which should be on the same network of Docker Compose. In docker-compose.yml I specify the name of the default network manually (to make sure the name is deterministic with no random strings added to it), ie:

networks:
  default:
    name: foo-network

I then try to start Chrome with:

    @Rule
    @JvmField
    val browser: BrowserWebDriverContainer = BrowserWebDriverContainer()
            .withDesiredCapabilities(DesiredCapabilities.chrome())
            .withNetworkMode("foo-network")

However, that does not work. When I use docker inspect on the Chrome image, the setting foo-network is completely ignored, and I get a new network with a random name, eg:

 "Networks": {
                "7af40cfa-f262-463c-accb-1707bdd8f2d9": {
                    "IPAMConfig": null,
                    "Links": null,
                    "Aliases": [
                        "tc-qEF38kvs",
                        "a8bd32b1f2f3"
                    ],
                    "NetworkID": "96313abc29bedbb992f754ba6684a3c8847bcd7f8bf9af547ce6fb38b0152a91",
                    "EndpointID": "6851d5ba06dda964677f57263a03806c47aea7d3a021fb2e71b3f14fe895664f",
                    "Gateway": "192.168.48.1",
                    "IPAddress": "192.168.48.2",
                    "IPPrefixLen": 20,
                    "IPv6Gateway": "",
                    "GlobalIPv6Address": "",
                    "GlobalIPv6PrefixLen": 0,
                    "MacAddress": "02:42:c0:a8:30:02",
                    "DriverOpts": null
                }
            }

Is there a better way to connect BrowserWebDriverContainer to an existing Docker Compose network? And in any case, if how I use withNetworkMode is wrong, it would be good if TestContainer threw an exception with some info.

TestContainer version: 1.9.1
Docker version: 18.06.1
OS: Mac 10.12.6

Beginne bei BrowserWebDriverContainer#withNetworkMode und DockerComposeContainer, reproduziere die Netzwerkdeklaration aus der bereitgestellten docker-compose.yml und untersuche die Netzwerke des erstellten Containers. Als erledigt gilt die Ermittlung, warum foo-network ignoriert wird, sowie die Festlegung des unterstützten Verbindungsverhaltens, einschließlich eines informativen Fehlers, wenn der Modus ungültig ist.
