AcrylicWindow on active has accent color instead of acrylic transparency on latest Windows 11 dev preview build

[SlackingVeteran]

With release of windows 11 back in Fall 2021 we know FluentWPF had some issues while dragging window around. Acrylic/Transparent part used to flicker between accent color and acrylic very rapidly. Attached video of old issue:

Today Windows 11 Build 22543.rs_prerelease.220122-2315 was released. Although since latest FluentWPF has that previous issue fixed by not moving entire window until mouse was release, it seems like Acrylic window is inheriting the accent color on Acrylic window 100% of the time (I am sorry if I am mixing things up right now, I haven't looked at how Acrylic window works these days because I am still using older version but I did look at some of the commits). Now with latest build we see following issue on both latest and older FluentWPF versions:

Second video .Net Core Sample app is built from master with no changes.

@sourcechord Do you have any idea what might be causing it to use Accent Color? I would rather prefer AcrylicWindow's Windows 7 behavior on Windows 11 until proper solution is found
