@Arlodotexe heard back from the platform team, this is a known issue and expected with 1.5. A fix should be coming in 1.6, so we can start testing that later as we see experimental/preview releases.

For now, let's just turn on the AoT compatible bit/annotations and get that checked-in.

Here's the error message from the CI:

ExtensionsComponent.Tests.FrameworkElementExtensionsTests.FrameworkElementExtension_RelativeAncestor_FreeParentBaseline_FrameworkElementExtensionsTests_Test 

This seems to be a transient error, so I'll rerun the ci and we'll address it directly if it reproduces consistently.
