Reproduction steps:
1. Create a new project
2. Add multiple Overlays to the Scene view
3. Dock Overlays to the corners and docking areas on left and right sides of Scene view
4. Resize left and right side docking areas to cover entire Scene view
5. Observe all Overlays

Actual result: Overlays docked to the corners get hidden or UI breaks so that not all elements are visible
Expected result: Overlays docked to the corners remain visible and UI doesn’t break
