Hi Team! I'm still new to ktor/kotlin, and have been playing around with the framework for websocket development. My current project is a websocket proxy (we accept a ws connection, and create a connection to another backend ws server, and route messages between them). The code works fine, but I'm having issues with setting up tests for this, specifically with trying to mock out the backend ws server with `externalServices`. This is the mock I have right now in my `testApplication`:
```externalServices {
    hosts("<ws://test.com>") {
        install(io.ktor.server.websocket.WebSockets) {}
        routing {
            webSocket("/") {
                this.send("hello")
            }
        }
    }
}```
My test will hang when it tries to connect to `<ws://test.com>` and eventually return a `io.ktor.client.network.sockets.ConnectTimeoutException: Connect timeout has expired [url=<ws://test.com>, connect_timeout=unknown ms]` error. Can `externalServices` mock out ws servers? If not, are there any suggestions on how to mock a ws server for testing? Thank you!

happy to post more code or logs if that's helpful
