FullScreen bug

[X-Yunner]

Describe the bug

I want to make FluentWindow fullscreen, and I just need to execute the code in order while I'm on Window

WindowStyle = WindowStyle.None;
 ResizeMode = ResizeMode.NoResize;
 viewModel.MainWindowWindowState = WindowState.Maximized;

But not on fluentWIndow, it won't cover the whole screen, there will be margins, I tried many times, only in this order to be full screen.

ResizeMode = ResizeMode.NoResize;
viewModel.MainWindowWindowState = WindowState.Maximized;
WindowStyle = WindowStyle.None;

It's strange

To Reproduce

private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
{
    if (viewModel.TitleBarVisibility == Visibility.Visible)
    {
        //viewModel.TitleBarVisibility =Visibility.Collapsed;
        WindowStyle = WindowStyle.None;
        ResizeMode = ResizeMode.NoResize;
        viewModel.MainWindowWindowState = WindowState.Maximized;

        //ResizeMode = ResizeMode.NoResize;
        //viewModel.MainWindowWindowState = WindowState.Maximized;
        //WindowStyle = WindowStyle.None;
    }
    else
    {
        viewModel.TitleBarVisibility  = Visibility.Visible;
        ResizeMode = ResizeMode.CanResize;
        WindowStyle = WindowStyle.SingleBorderWindow;
        viewModel.MainWindowWindowState = WindowState.Normal;

    }
}

Expected behavior

 WindowStyle = WindowStyle.None;
 ResizeMode = ResizeMode.NoResize;
 viewModel.MainWindowWindowState = WindowState.Maximized;
``` can fullscreen
