Reproducible with: 2020.3.23f1, 2021.2.4f1, 2022.1.0a16
Couldn't reproduce with: 2019.4.33f1 (no Properties window)

Notes:
1. In 2020.3.23f1 and 2021.2.4f1, the same GameObject or the Parent Canvas also needs to be selected in the Hierarchy window
2. In 2020.3.23f1 and 2021.2.4f1, the issue is not reproducible with Canvas, only GameObjects that have Canvas Renderer and a Component that depends on it
3. In 2022.1.0a16, the issue is reproducible with GameObjects that have a Canvas Renderer or a Canvas Component
