How to reproduce:
1. Create a new Unity project
2. In the Hierarchy, add enough GameObjects to fill in the whole window
3. Create another GameObject that doesn't fit the window
4. Observe the results

Expected results: The Hierarchy automatically scrolls to focus on the new GameObject
Actual results: The Hierarchy doesn't scroll automatically and the new GameObject is not instantly visible

Reproducible with: 6000.3.0a2, 6000.3.0a6
Can't test with: 6000.0.56f1, 6000.1.16f1, 6000.2.1f1, 6000.3.0a1 (Hierarchy V2 is not available) 

Reproducible on: macOS Sequoia 15.5 (M1)
Not reproducible on: No other environment tested

Note: When creating the nested GameObject with many layers, the Hierarchy should also scroll horizontally. This bug persists across both V1 and V2 Hierarchies, but vertical scrolling doesn't work correctly only in V2.
