Missing script component has no header in the Inspector when its script file is deleted

How to reproduce:

1. Create an empty project and open it
2. In the Hierarchy tab, create an empty GameObject (right-click > “Create Empty”)
3. In the Inspector tab of newly added GameObject, click “Add Component” > select “New script” > name it “NewMonoBehaviourScript” > “Create and Add”
4. In the Project tab, delete “NewMonoBehaviourScript.cs” (right-click > “Delete”)
5. In the Hierarchy tab, select GameObject
6. Observe the result in the Inspector tab

Actual result: The missing script component draws no header, so it's impossible to remove the component from the three-dots menu
Expected result: The missing script component shows its header with an accessible menu, so it can be removed
