JS Binding: JsValue("Command tauri not found") error when trying to emit or listen to events on Tauri v2.0.0-alpha.9

As the title says listening or emitting with tauri 2.0.0-alpha.9 event does not work with error: JS Binding: JsValue("Command tauri not found").

For example with such code:

async fn listen_to_event() -> Result<(), Error> {
    let s = listen::<String>("event-name").await?; // Fail here
    Ok(())
}

Invoking commands works fine and I have not tested other stuff. I know it's alpha and things can get broken but is there at least some workaround?

I managed to do workaround by manually implementing listen using wasm_bindgen with something like that:

#[wasm_bindgen]
extern "C" {
    #[wasm_bindgen(js_namespace = ["window", "__TAURI__", "event"])]
    async fn listen(event: &str, listener: &js_sys::Function) -> JsValue;
}
pub async fn do_something_on_event() -> Result<(), Error> {
    let closure = Closure::wrap(Box::new(move |event: JsValue| {
        let event: tauri_sys::event::Event<String> = match serde_wasm_bindgen::from_value(event) {
            Ok(event) => event,
            Err(e) => {
                // Some error handling...
                return;
            }
        };
        let payload = event.payload;
        // Do something with payload
    }) as Box<dyn FnMut(JsValue)>);

    tauri_sys::tauri::invoke(
        "command",
        &Payload {
            // Payload params
        },
    )
    .await?;
    let _ = listen("event", closure.as_ref().unchecked_ref()).await;
    closure.forget();
    Ok(())
}

I actually end up better for me as I could more adjust event handling. I leave issue opened as lib's function does not work
