Hi all, I am trying to determine programmatically what outputs are expected to be added/changed/removed when running `pulumi up` and I was surprised to see that `pulumi preview` doesn't list changes to existing outputs: <https://github.com/pulumi/pulumi/issues/20087> . Is this expected behavior? Either way, what would it take to change that? (I'd be happy to contribute a PR if the implementation is straight-forward enough for a newcomer like me.)

It's probably just something in the display layer omitting it in preview mode. I think there should be enough engine events to tell what's changed.

Would you happen to know where in the code I could start looking to fix this?

Somewhere in <https://github.com/pulumi/pulumi/tree/master/pkg/backend/display> I'd guess
