How to reproduce:
1. Open any project with Visual Effect Graph added
2. Create a Prefab and open it in context or isolation
3. Right-click in Hierarchy and select "Visual Effects" > "Visual Effect"
4. Observe created Visual Effect Graph in Scene Hierarchy
Actual result: Visual Effect is created in Scene Hierarchy and not in Prefab Hierarchy when created in Hierarchy, if it is created by right-clicking the Prefab Parent GameObject instead, it is created as a child
Expected result: Visual Effect is created as a child of the Prefab when created by right-clicking anywhere in Prefab Hierarchy
