targetCreatedHandler triggers UnhandledPromiseRejectionWarning

#### What are you trying to achieve?
Running tests on the CI with minimum text output to the console

#### What do you get instead?
Though the tests pass the UnhandledPromiseRejectionWarning message creates redundant text output.

> Provide console output if related. Use `--verbose` mode for more details.

```bash
(node:21420) UnhandledPromiseRejectionWarning: frame.frameElement: Frame has been detached.
at C:\Users\...\..\...\node_modules\codeceptjs\lib\helper\Playwright.js:2643:46
(node:21420) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag --unhandled-rejections=strict (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 4)
```

> Provide test source code if related

```js
// paste test
```

使用所示的 Playwright 配置，以最少的控制台输出运行 CI 测试，然后检查 targetCreatedHandler 以及 Playwright.js 堆栈中第 2643 行附近的位置。测试在没有 UnhandledPromiseRejectionWarning 的情况下仍然通过，即表示完成。
