I think a complete fix is to let `Union` has fresh attribute IDs for its output, as technically `Union`'s outputs are totally different from its first child's outputs. It's going to be a big change so we should only do it in the master branch. Can we open a PR for 3.0 with this surgical fix? Let's make sure the test still passes with this fix in 3.0. -- This is an automated message from the Apache Git Service.
