all goroutines are dead asleep - deadlock! wasm docs

I'm trying to do the next:
### Client Code:
```go
//go:build js && wasm

package main

import (
"context"
"log"
"syscall/js"

"nhooyr.io/websocket"
)

func main() {
ctx := context.Background()
window := js.Global()
window.Set("goWS", js.FuncOf(func(_ js.Value, args []js.Value) any {
conn, _, err := websocket.Dial(ctx, args[0].String(), nil)
if err != nil {
log.Fatal(err)
}
goWSObject := window.Get("goWS")
goWSObject.Set("send", js.FuncOf(func(_ js.Value, args []js.Value) any {
if err := conn.Write(ctx, websocket.MessageText, []byte(args[0].String())); err != nil {
log.Fatal(err)
}
return nil
}))
goWSObject.Set("waitMessage", js.FuncOf(func(_ js.Value, _ []js.Value) any {
_, bb, err := conn.Read(ctx)
if err != nil {
log.Fatal(err)
}
return bb
}))
return nil
}))
waitCh := make(chan struct{})
<-waitCh
}
```
### `index.html`:
```html

goWS


const go = new Go();
WebAssembly.instantiateStreaming(fetch("/assets/app.wasm"), go.importObject)
.then(res => go.run(res.instance))

```
### Server code:
```go
package main

import (
"context"
"net/http"

"nhooyr.io/websocket"
)

func main() {
ctx := context.Background()

http.HandleFunc("/ws-chat", func(w http.ResponseWriter, r *http.Request) {
conn, err := websocket.Accept(w, r, &websocket.AcceptOptions{
InsecureSkipVerify: true,
})
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
_, bb, err := conn.Read(ctx)
if err != nil {
conn.Close(websocket.StatusInternalError, err.Error())
return
}
wr, err := conn.Writer(ctx, websocket.MessageText)
if err != nil {
conn.Close(websocket.StatusInternalError, err.Error())
return
}
wr.Write(bb)
wr.Close()
conn.CloseNow()
})
http.ListenAndServe(":8080", http.DefaultServeMux)
}
```
Also I'm going to attach my Makefile so you can see the commands when I'm compiling:
```make
build_client:
GOOS=js GOARCH=wasm go build -o dist/assets/app.wasm cmd/go-ws-client/main.go
cp $(go env GOROOT)/misc/wasm/wasm_exec.js dist/assets/

build_server:
go build -o dist/bin/app-server cmd/go-ws-server/main.go
```
### Structure of `dist` folder:
```
dist/
- assets/
- app.wasm
- wasm_exec.js
- bin/
- app-server
- index.html
```
But i'm getting the following errors after calling `window.goWS("ws://localhost:8080/ws-chat")` from the firefox browser's console:
### Console:
```
> window.goWS("ws://localhost:8080/ws-chat")
