vite dev-server doesn't allow lazy loaded modules debugging

### Command

serve

### Is this a regression?

- [X] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

16 (with webpack)

### Description

If you try to debug a lazy loaded component form vscode, and set a breakpoint, say into ngOnInit of the component, vite never stops when reaches the breakpoint.

It's difficult to give more data, as
- there is no way to change vite config (to add verbosity, for example)
- looking in the output window, there is nothing tha allows to see vite output

### Minimal Reproduction

create a new 18.2 application, add a lazy loaded route, start debugging from visual studio code, set a breakpoint on a line inside the lazy loaded component.
the component renders correctly but vite never stops for the breakpoint.
Here a repository that reproduces the bug. I tested it only in Vscode.

リンクされている lazy-loading の再現手順と、Vite を使用する Angular CLI の `serve` パスから始めます。VS Code の `launch.json` 構成を実行し、lazy-loaded コンポーネントにブレークポイントを設定して、メインバンドルのブレークポイントと比較します。lazy-loaded コンポーネントのブレークポイントでデバッグが停止するか、関連する出力とともに制限事項が文書化されていれば完了です。
