CanvasGroup settings applies to Canvas components. The child object in this example does not have a Canvas component on it, only a CanvasGroup - that won't do anything. CanvasGroup needs to be accompanied by a Canvas, otherwise it's useless.

How to reproduce:
1. Open the attached project "2022.3_Test_CanvasGroup.zip"
2. Open Assets/Scenes/SampleScene.unity

Expected results: A Circle is displayed in the Game view window
Actual results: Circle is not displayed in the Game view window

Reproducible with: 2021.3.35f1, 2022.3.19f1, 2023.2.9f1, 2023.3.0b6

Reproducible on: Windows 11 22H2
