Puppeteer fails subsequent tests if beforeunload popup shown

#### What are you trying to achieve?
When testing a page which shows a popup on unload (`beforeunload` event), CodeceptJS fails if `restart: false` is set.

The issue is not present when `restart: true` is set.

Additionally, process exits with code 0, indicating a success.

I couldn't successfully accept the popup, and I tried at the end of the first test, at the beginning on the second test, and in `_before` handler.

Example project: https://github.com/dejanceltra/codeceptjs-popup-issue
CodeceptJS run: https://github.com/dejanceltra/codeceptjs-popup-issue/runs/3836071868

#### What do you get instead?

```bash
npx codeceptjs run
shell: /usr/bin/bash -e {0}

### Details

* CodeceptJS version: 3.1.2
* NodeJS Version: v16.9.1
* Operating System: macOS | Linux
* puppeteer: 10.4.0
* Configuration file:

```js
const { setHeadlessWhen } = require('@codeceptjs/configure');

// turn on headless mode when running with HEADLESS=true environment variable
// export HEADLESS=true && npx codeceptjs run
setHeadlessWhen(process.env.HEADLESS);

exports.config = {
tests: './*_test.js',
output: './output',
helpers: {
Puppeteer: {
restart: false,
url: 'http://localhost',
show: false,
windowSize: '1200x900'
}
},
bootstrap: null,
mocha: {},
name: 'puppeteer-test',
plugins: {
pauseOnFail: {},
retryFailedStep: {
enabled: true
},
tryTo: {
enabled: true
},
screenshotOnFail: {
enabled: true
}
}
}
```

Reproduce the restart:false scenario from the provided HTML and JavaScript snippets, then inspect lib/helper/Puppeteer.js around the dialog handling reported at line 483 and lib/listener/steps.js around line 55. Verify that a beforeunload popup does not break the following test or cause duplicate completion errors, and confirm the run reports the correct failure status.
