👋 Hi there. I'm trying to use kotest-extensions-testcontainers in AnnotationSpec driven test in order to test against Kafka container. I have more or less something like this in my code:

class KafkaContainerDrivenTest: AnnotationSpec() {
    private val testNetwork = Network.newNetwork()
    
    private val kafkaContainer = install(ContainerExtension(beforeStart = { println("before start")}, afterStart = { println("after start")}, container = KafkaContainer(DockerImageName.parse("confluentinc/cp-kafka:6.2.1")))) {
        println("configuring")
        withExposedPorts(9093)
        withNetwork(testNetwork)
        withNetworkAliases("kafka")
    }
    ...
}

judging from ContainerExtension.mount() function and std output (where I see that 'before start' and 'after start' hooks are running before 'configuring' block) how can I ensure that my Kafka container is properly configured before it gets started. Looks like container is started before its configuration lambda gets executed. I am expecting following output:

configuring
before start
after start

Please correct me if I'm wrong. I'm struggling with getting this properly configured and running in tests along with toxiproxy. I am on "io.kotest.extensions:kotest-extensions-testcontainers:2.0.2 and io.kotest:kotest-runner-junit5:5.8.1.

small update - looks like the order of execution has been changed https://github.com/kotest/kotest-extensions-testcontainers/commit/5c2db6cb409a25aaf9a619fd664a60c5f1adc1d4

@sam can you shed some light on it in a spare moment?
