Repo steps:
# Open Unity Scene
# Go to camera in the hierarchy and delete it
# Click on the "game" view next to "scene" at the top of the editor
# Viewport should display "Display 1 Camera not rendering" 
# Expand the project menu upwards until it cant go any further

Expected Result: UI stops moving and does not overlap with top of editor

Actual Result: UI overlaps with top of editor
