[bug] new webview added to the window does not appear on top (Windows)

[seb-hernandez]

Describe the bug

I am creating a window and adding my main webview to it. After that, I am adding a second webview. On macOS, this new webview overlaps the main webview (appears on top). However, on Windows, it gets positioned behind the main webview. To make the second webview visible on Windows, I need to manually set the size of the main webview to zero width and height (making it "disappear").

I would like to know which behavior should be considered the default: the one on macOS or on Windows. Personally, I prefer the way it works on macOS.

let window = WindowBuilder::new(app, "main")
    .inner_size(x, y)
    .title("title")
    .build()
    .unwrap();

let main_webview_builder =
    WebviewBuilder::new("main", WebviewUrl::App("index.html"))
        .auto_resize();

window
    .add_child(
        main_webview_builder,
        PhysicalPosition::new(0, 0),
        PhysicalSize::new(x, y),
    )
    .unwrap();

let new_webview_builder =
    WebviewBuilder::new("new", WebviewUrl::External("https://google.com"))
        .auto_resize();

window
    .add_child(
        new_webview_builder,
        PhysicalPosition::new(0, 0),
        PhysicalSize::new(x, y),
    )
    .unwrap();
