Research direction

Start by reproducing the crash on a Windows 11 21H2 build 22000 VM with .NET 8 and the 0xFFFFFFFE input. Review the referenced WPF-UI pull request 1122 and the targeted approach in PowerToys pull request 33687, then verify that the titlebar no longer crashes on that environment.

Describe the bug

On Win11 21h2 (build 22000), it looks like the code from https://github.com/lepoco/wpfui/pull/1122/files#diff-196b404f4db09632665ef546da6c8e57302b2f3e3d082eb4b5c295ae3482d94a doesn't quite fix the issue. When we released to the wild in 0.82, we started seeing win11 build 22000 failures.

I can reproduce it on a VM.

https://github.com/microsoft/PowerToys/pull/33687 has a bit more of a targeted hack to resolve the issue.

To Reproduce

Spin up a 21h2 VM and you'll see it fail if you pass in 0xFFFFFFFE
