Uncaught TypeError: Failed to construct 'Worker'

I tried minimum example. (on Chrome 69/Mac)

// src/index.js
const worker = new Worker("./worker.js", { type: "module" });
worker.onmessage = event => {
  console.log("response: " + event.data);
};
worker.postMessage(0);

// webpack.config.js
const HTMLPlugin = require("html-webpack-plugin");
const WorkerPlugin = require("worker-plugin");

module.exports = {
  mode: process.env.NODE_ENV || "development",
  plugins: [new HTMLPlugin(), new WorkerPlugin()]
};

Compile success but I got this error on browser.

Uncaught TypeError: Failed to construct 'Worker': Module scripts are not supported on DedicatedWorker yet. You can try the feature with '--enable-experimental-web-platform-features' flag (see https://crbug.com/680046)

Build result is here

/* WEBPACK VAR INJECTION */(function(__webpack__worker__1) {const worker = new Worker(__webpack__worker__1, { type: "module" });
// ...

I tried enable-experimental-web-platform-features but it does not work too. (and ChromeCanary too)

I think, it is lack of some pre-conditions.
