Current Behavior

This PR #1630 has broken ViewTreeObserver.IOnGlobalLayoutListener on Android API 29 and (protentional below).

var listener = new WindowInsetsOldApiListener(activity.Window.DecorView);
activity.Window.DecorView.RootView?.ViewTreeObserver?.AddOnGlobalLayoutListener(listener);

Expected Behavior

ViewTreeObserver.IOnGlobalLayoutListener works as before the PR #1630

Environment

• .NET MAUI CommunityToolkit: 9.0.3 and 9.1.0
• OS: Windows
• .NET MAUI: .NET 8.0.91

Anything else?

Can't confirm which line of code in the PR has broken ViewTreeObserver.IOnGlobalLayoutListener. Also can't easily test the bug on Android emulators API 29 and below due to an old version of WebView on such emulators. I have a project using BlazorWebView. As I get more info I'll be back.
What I can say for sure is reverting the PR #1630 and using CommunityToolkit as a .dll makes ViewTreeObserver.IOnGlobalLayoutListener work normally.

Thanks @evgenyvalavin that sounds plausible. Would you be willing to provide a sample or PR to help solve this?

I have a concern now whether .AddFlags() will solve the problem

I'll add more info when I know more. Hope this bug will catch someone's attention who came across the same problem as me
