Components are flattened in the Inspector when using a custom initializer

How to reproduce:
1. Open the “InspectorOverlappingIssue“ project
2. Open the “Assets/BugReport/BugReportScene.unity” scene
3. In the Hierarchy window select the “PlayerNameDisplayers” GameObject
4. In the Inspector window locate the “Player Name Displayer” script Component
5. Expand the “Init” section
6. Make sure the Inspector window is left open
7. From the Project window drag the “Assets/BugReport/PlayerNameDisplayer.cs” script on the “PlayerNameDisplayers” GameObject
8. Observe the Inspector window

Expected result: All the Components are spaced out evenly
Actual result: All the Components are flattened together

Note: Reselecting the GameObject in the Hierarchy window resolves the issue
