Target:
Windows

I have a tray application. When I open window from tray context menu first time -> the window position is "center" (this is expected). But if I close the window and open again -> the window position becomes "top-left" (seems bug).

Steps to Reproduce:

Create a simple desktopizer

/// <summary>
/// Provides functionality to bring the ASP.NET Core application to desktop.
/// </summary>
public class Desktoper
{
  private readonly MenuItem[] _menuItems;
  private BrowserWindow _testWindow;

  public Desktoper()
  {
    var testWindowOptions = new BrowserWindowOptions
    {
      MinWidth = 800,
      MinHeight = 400,
      Width = 800,
      Height = 400,
      Frame = false,
      Icon = _trayMenuSettingIcon,
      Fullscreenable = false
    };

    _menuItems = new[]
    {
        Label = "Test",
        Icon = _testMenuSettingIcon,
        Click = async () => _testWindow = await Electron.WindowManager.CreateWindowAsync(testWindowOptions)
      },
      new MenuItem
      {
        Type = MenuType.separator
      },
      new MenuItem
      {
        Label = _localizer["Exit"],
        Icon = _trayMenuExitIcon,
        Click = () => Electron.App.Quit()
      }
    };
  }


  /// <summary>
  /// Brings the ASP.NET Core application to desktop.
  /// </summary>
  public void Desktopize()
  {
    Electron.WindowManager.IsQuitOnWindowAllClosed = false;
    Electron.Tray.Show("path/to/tray-icon.png", _menuItems);
  }


  public void CloseSettingsWindow()
  {
    _testWindow?.Close();
  }
}

Desktopize method should be called from Startup class Configure method. CloseSettingsWindow method is use when I press the Cancel button (see gif below).
Run app and open the test window via tray context menu -> window will be positioned on the center of the screen.
Close the test window and repeat the step 3 -> window will be positioned on top-left of the screen.

@Tum4ik commented on GitHub (May 29, 2019):

Actually it could be fix by

new MenuItem
{
  Label = _localizer["Settings"],
  Icon = _trayMenuSettingIcon,
  Click = async () =>
  {
    _settingsWindow = await Electron.WindowManager.CreateWindowAsync(_settingsWindowOptions);
    _settingsWindow.Center(); // <---- Fix
  }
},

But I don't know. It seems it is not obvious.
