Regression: Windows are always "inactive"

[Marv51]

Describe the bug

In WinAppSDK 1.6.1, I am unable to scroll any scroller control using mouse wheel if mouse option to scroll inactive windows is OFF.

This was reported as #8764 and fixed before, but now this is broken again. There are multiple people that experience this regression who commented in the original issue.

Steps to reproduce the bug

1. Go to Windows Mouse settings
2. Disable scroll of inactive windows on mouse over
3. Open a WinUI 3 app.
4. Nothing will scroll using mouse wheel, even if focused.

Expected behavior

The same that happens for any other software: scroll working when window is active.

Screenshots

NuGet package version

WinUI 3 - Windows App SDK 1.6.1: 1.6.240923002

Windows version

Windows 11 (22H2): Build 22621

Additional context

I mostly copy and pasted this issue from the original report in #8764 from 2022, as it describes the issue well. But I am worried that comments on a closed issue are not getting the urgent attention that this regression needs.

@hiteshkrmsft Can you clarify what version this was fixed in and if any developer steps are required?

My app built with the latest WinAppSDK 1.6.6 still reproduces this regression. The latest WinUI 3 Gallery version from the Store also shows this broken behavior.
