[bug] window size is not correct since v2.1.1

[zhangsan946]

Describe the bug

While creating the main WebviewWindow with the following snippet, it works well on Windows.

let main_window = tauri::WebviewWindowBuilder::new(
      app_handle,
      "main",
      tauri::WebviewUrl::default(),
  )
  .fullscreen(false)
  .maximizable(false)
  .resizable(false)
  .visible(false)
  .title(app_handle.package_info().name.as_str())
  .position(0., 0.)
  .inner_size(330., 620.)
  .build()?;

let window_size = main_window.outer_size()?;

But on Linux(ubuntu 22.04), main_window.outer_size() returns (0,0). After some debug, it shows to be releted with visible config. It seems not to be able to get the window outer size before the window shows. It used to work before tauri v2.1.1.

On MacOS, the inner_size would include the height of window title bar which differs from Windows and Linux behavior. I remember that the inner_size behaves the same on these three OS some time ago.

Reproduction

Please refer to the description section.
