Does BP Nativization support UMG Assets?

Can UUserWidget Assets be nativized?
When cooking a UUserWidget asset, Automation Tool gives me Warning, “Nativization and Fast Widget Creation is not supported at this time.”
However, regardless of the warning, the cooker creates a nativized source code for the widget in Intermediate Directory.

Can I get some confirmation whether UMG is supported for BP Nativization or not?

UMG nativization is supported. What isn’t supported is both Nativization & Fast Widget Creation at the same time. So when I nativize my UMG widgets I disable that like so:

Thank you for you reply.

I gave up nativing UMG widgets because there are too many cooking failures+ run time crashes.
I hope it will be better in 4.19.
