Graphics Tier Settings Editor has no vertical scrollbar even though Settings have been reordered to be vertical

How to reproduce:
1. Open any project
2. Navigate to Edit > Project Settings > Tier Settings > Open Editor
3. Observe the Tier Settings Window, resize it

Actual result: No horizontal scrolling function is enabled and no scroll bar is enabled
Expected result: Tier Settings window has been reordered to be vertical, so vertical scrolling and scroll bar should be enabled
