[bug] Specifying `focus` window config to false in Tauri config cannot disable focus on startup under Windows

Describe the bug

In Tauri config file, there is a focus option in window configuration, which supposedly specifies the focus state when the window is initially created. However, the current behaviour is no matter it's set to true or false in the config file, when the dev server starts, the program always gain focus. Setting this to false is the same as true.

If instead, remove the windows object from config file and use Rust to create window with WebviewWindowBuilder, the window can be set to not focus when created with .focused(false), and setting config file should have the same effect, which is not the case.

Reproduction

Create a test project with pnpm create tauri-app
Choose some sane defaults
Install dependencies with pnpm install, run the dev server. The default config should focus the window when launched

Change the windows config as follows:

  "windows": [
  {
    "title": "tauri-app",
    "width": 800,
    "height": 600,
    "focus": false
  }
],

Restart the server, the app window still get focused despite the config is set to false

Expected behavior

Window should not be focused when focused is set to false.

It should be the same as created manually with:

    tauri::Builder::default()
        .plugin(tauri_plugin_shell::init())
        .invoke_handler(tauri::generate_handler![greet])
        .setup(|app| {
            let 
            _webview_window = tauri::WebviewWindowBuilder::new(app, "label", tauri::WebviewUrl::App("index.html".into())).focused(false)
            .build()?;
            Ok(())
        })
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
