worker-loader doesn't work properly after restart

I'm trying to use web with vue-cli project.

My worker is in file user.worker.js. When I run vue-cli-service serve for first time it works, but after restart webpack tries to load user.worker.worker.js and cant because such file doesn't exist. If I rename or move the file it works for first time but after restart fails again.

App.vue

<template>
  <div id="app"></div>
</template>

<script>
import Worker from "@/user.worker";

export default {
  name: "App",
  created() {
    const inst = new Worker();
    inst.postMessage({
      path: `some data`,
    });
  },
};
</script>

user.worker.js

onmessage = async ({ path }) => {
  postMessage({ path });
};

vue.config.js

module.exports = {
  chainWebpack: (config) => {
    config.module
      .rule("worker")
      .test(/\.worker\.js$/)
      .use("worker-loader")
      .loader("worker-loader")
      .end();
  },
};
