How to reproduce:
1. Open the “ReproProject“ project
2. Open the “TestMultiplayer“ scene
3. Open the “NetworkGameManager“ GameObject in the Inspector window
4. Expand the “Network Game Manager“ Script Component

Expected result: All the serialized fields are displayed in the Inspector window
Actual result: Only a few serialized fields are displayed and the “Add Component“ button is clipping through them

Reproducible with: 2021.3.32f1, 2022.3.12f1, 2023.1.18f1
Not reproducible with: 2023.2.0b16, 2023.3.0a12
Fixed in: 2023.1.19f1

Reproducible on: macOS 13.5.2 (Intel)

Notes:
- During Play mode, the “Network Game Manager“ Script Component is displayed correctly
- Workaround 1: Inspect the “Network Game Manager“ Script Component with the Inspector window with Debug mode toggled on
- Workaround 2: Enter Play mode then exit Play mode, after that the “Network Game Manager“ Script Component will be displayed correctly, and the issue will not be reproducible anymore
