Can we add a test for this like this: https://github.com/dotnet/maui/blob/main/src/Controls/tests/DeviceTests/Elements/Page/PageTests.cs#L67-L84

Preferably we need a way to see if a property changes that a set of handler events fire, but this is technically better as we check for colors.

Updated adding device tests.

The test logic should be cross-platform, so should we move the test into the shared code so it runs on all platforms?

Yeah, moved to shared code to allow run it on all the platforms. Waiting for the build.
