UI is still visible in the Game view during runtime when Camera Component's Render Type is set to Overlay and Canvas Group's Alpha value is animated from 1 to 0 on scene change

How to reproduce:
1. Open the user's attached "Fading Animation.zip" project
2. Open the "Base" Scene
3. Enter Play Mode
4. Observe the Game view

Expected result: "This is Scene 2" text is not visible when Canvas Group's Alpha value is animated to 0
Actual result: "This is Scene 2" text is visible when Canvas Group's Alpha value is animated to 0

Reproducible with: 7.2.0 (2019.3.0f6), 7.3.1 (2019.4.8f1), 8.2.0 (2020.1.2f1), 10.0.0-preview.26 (2020.2.0a20)
Not reproducible with: 4.10.0-preview (2018.4.26f1), 7.1.8 (2019.3.0f6)

Notes:
- The issue is not reproducible with the built-in RP
- The issue is not reproducible with HDRP
- The "Panel" GameObject is not visible in the Scene view, only in the Game view
- If the Canvas Group Component's Alpha value is changed in the Edit Mode manually to 0, the "Panel" GameObject is not visible in the Game view
- If the "Main Camera" GameObject's Camera Component's Render Type is set to "Base", the issue is not reproducible
