Game View Stats window has inconsistent scrollbar behaviour when opening different foldouts

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Click the "Stats" button in the Game View toolbar
3. Open the "Scene" foldout
4. Close the "Scene" foldout
5. Observe the Stats window
6. Open the "Memory" foldout
7. Repeat step 5
8. Open the "Animation and Meshes" foldout
9. Repeat step 5

Actual results: When the "Scene" foldout is open, there is no scrollbar and the Stats window becomes bigger, when the "Memory" foldout is open, a scrollbar appears instead, and when the "Animation and Meshes" foldout is opened the scrollbar disappears

Expected results: All foldouts should be consistent, either using a scrollbar or making the window bigger
