Repository: node
Issue: NodeWorker domain pauses on start unless there's an `--require`'d program in NODE_OPTIONS
Labels: worker

* **Version**: 16.2.0
* **Platform**: Microsoft Windows NT 10.0.19042.0 x64
* **Subsystem**: inspector

This is probably similar to https://github.com/nodejs/node/issues/38420, but reporting it for visibility.

### What steps will reproduce the bug?

In a debugger that's worker_thread capable, namely in VS Code:

1. Create these files:

    **index.js**

    ```js
    const { Worker, isMainThread } = require('worker_threads');

    if (isMainThread) {
      const worker = new Worker(__filename, {
        // env: {}
      });
    } else {
      console.log('hello world');
    }
    ```

    **empty.js**

    ```
    ```

    **.vscode/launch.json**

    ```json
    {
      "version": "0.2.0",
      "configurations": [
        {
          "name": "Launch Program",
          "program": "${workspaceFolder}/index.js",
          "request": "launch",
          "type": "pwa-node"
        }
      ]
    }
    ```

2. Debug it (by hitting F5). It should run through and exit.
3. Uncomment line 5. Debug it. It pauses when the worker thread is launched. :bug:
4. Replace line 5 with `env: { NODE_OPTIONS: `--require ${__dirname}/empty.js` }`. Debug it. It no longer pauses.


### How often does it reproduce? Is there a required condition?

100%

### What is the expected behavior?

In no case should the debugger pause when entering the worker_thread.

### What do you see instead?

It pauses if there is nothing --required in the NODE_OPTIONS. But even requiring an empty file, which I would expect to have no effect, fixes the issue.

### Additional information

This is the "paused" event sent from Node in the `env: {}` case:

You can add `trace: true` to the launch.json, which will produce a file containing all traffic to and from the debugger that can be inspected [here](https://microsoft.github.io/vscode-pwa-analyzer/index.html).

Note that the program is **not** launched with --inspect-brk (in which case this behavior would be expected)
