[.NET 9.0 Preview 7] .NET MAUI Windows App (WinUI 3) and regular WinUI 3 App don't remember the display in a multi-display setup, but always open in the main display

[TommiGustafsson-HMP]

Describe the bug

Setup

Hardware

A development laptop and an external display connected to an HDMI connector.

Software

• .NET 9.0 Preview 7
• Visual Studio 2022 17.12.0 Preview 1.0

Bug

When I create an empty .NET MAUI 9.0 Preview 7 App on Windows or an empty WinUI 3 App, they open up in the main display (laptop). If I move the app to the secondary display (external display) and close it there, it still opens in the main display (laptop) the next time I open it.

Steps to reproduce the bug

1. Create an empty .NET MAUI App or WinUI 3 packaged App in Visual Studio 2022 Preview.
2. Start the app by pressing the green debug button.
3. Move the app to the secondary display (external display).
4. Close the app.
5. Open the app again either by pressing the green debug button or from the start menu.
6. The app appears again in the main display.

Expected behavior

The app remembers its display position and appears in the secondary display.
