We're still working on testing the Toolkit against 1.6-preview1, see our tracking issue here: CommunityToolkit/Tooling-Windows-Submodule#205

We've heard this from PowerToys as well, so it'll be good to keep this as a tracking issue on the WinUI side.

It's unclear if this is just an issue with version matching and the need for the toolkit to be built against the same version with the fix for microsoft/microsoft-ui-xaml#8810 (ADO 46368821), a regression from that, or something else.

First step is for us to finish getting a clean build of the Toolkit on 1.6-preview1 to investigate more and see if we see this same issue when the versions of the dependent SDK match.

We may have local bits now on 1.6-preview1 (and just our CI still failing); so we're investigating if we see this behavior with that local build. Latest discussion on getting a build from our CI is here: CommunityToolkit/Tooling-Windows-Submodule#195 (comment)

Arlo (@Arlodotexe) provided a repro for this scenario with his locally built bits of the WCT built against preview1. I've posted them in the ADO. I can confirm we still see the same behavior mentioned here, so seems like a regression somewhere and most likely independent of the other issues we've had building to this point.

Thanks Evelyn Wu (@evelynwu-msft) and Manodasan Wignarajah (@manodasanW) for your help here! Mano provided me the change to the target and I was able to validate this fix on my machine against the preview1 bits. We'll see if we can work to validate the final bits ahead of release as well just to triple-check things look all good.
