How to reproduce:
1. Open the attached “IN-131475” project
2. Open the “SampleScene”
3. Go to Edit > Preferences > General > New Hierarchy
4. Enable “Use new Hierarchy window”
5. Hold the Alt button on the keyboard and expand all of the children of both “Generated_ComplexRoot” GameObjects
6. Right-click at the top of the Hierarchy window
7. Enable all information columns (active, layer, static, etc.)
8. In the Hierarchy window, while moving the mouse quickly, click and drag any GameObject
9. Observe the cursor

Actual result: No GameObject reference is held by the cursor until you drag the cursor over the Hierarchy window
Expected result: A reference to the GameObject is grabbed and can be dragged

Reproducible with: 6000.3.0a2, 6000.3.7f1, 6000.4.0b7, 6000.5.0a6
Could not test with: 2023.1.0a1, 6000.0.67f1 (New Hierarchy window was added in version 6000.3.0a2)

Reproducible on: Windows 11
Not reproducible on: No other environments tested

Notes:
- This issue does not reproduce if the extra information columns (active, layer, tag, etc.) are off
- This issue does not reproduce if the drag starts outside the Hierarchy window
- It is affected by the complexity of the hierarchy
- It may take a few tries of quick dragging before the issue reproduces
