    Yes, please backport this to 2018.3.X.
    I wanted to upgrade to 2018.3.7 following the news of the remote code execution security warning, but this bug is just gonna break so much of our UI.

    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.
