worker-loader doesn't work properly after restart - vue.js

Question

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();
},
};
