WebView2 DefaultBackgroundColor

[BlameTwo]

Describe the bug

I can't make the background color of WebView2 transparent, even though I'm not loading any html content

My development environment: Visual Studio 2022 preview
WindowsAppSdk Nuget Version 1.6.241114003

It is worth noting that I turned on AOT and tried to use P/Invoke to change the current window relationship to child window and parent window (modal).

Steps to reproduce the bug

1. According to my development environment
2. Create a WinUI project
3. Load a web page

Expected behavior

He should be a normal transparent color
