Come on, Unity. Please backporting this to Unity2018.3.X. If not, so many projects could not be use Unity2018.3.X.
This issue is a very serious and used common case. For example, split canvas and simply control show/hide. Strategy fo split canvas also useful render together Particle System, SpriteRenderer. So so many common logic have to be change, there are not a simply solver.
I have a some dirty solving way that link CanvasGroup like chain(What the!), and use it before we decide to upgrade Unity 2019.X(of course, I thought we can not upgrade before be regular stage). But in this case also have a lot of problem in case by case.
