Reproduction steps:
1. Create a new High Definition 3D project and ensure “Use new Hierarchy window” is enabled (Edit > Preferences… > General)
2. Create any GameObject that has more than one Component in the Inspector
3. Duplicate newly created GameObject multiple times until a scrollbar appears in the Hierarchy
4. Press “ctrl/cmd + a” to select all GameObjects
5. Deselect all GameObjects that are not duplicates
6. Observe the Inspector
Actual result: Only the Transform Component and “Components that only exist on some of the selected objects can’t be multi-edited” message are displayed in the Inspector
Expected result: All Components that exist on the selected GameObjects are displayed in the Inspector
