### Issue Details

* **Electron Version:**
  * 9.1.1
  * 10.0.0-beta.4
* **Operating System:**
  * Linux x64

### Expected Behavior

Don't crash when `nodeIntegrationInWorker` is `true` and a service worker is being registered. :slightly_smiling_face:

### Actual Behavior

A crash occurs once the service worker is attempted to be registered (blank page, DevTools disconnects).

### To Reproduce

Attempt to register a service worker with `nodeIntegrationInWorker` set to `true`.

```sh
$ git clone https://github.com/lgrahl/electron-node-integration-service-worker-crash
$ npm install
$ npm start
```
