Inspector Framework

2. Open the "Done_Main" Scene
3. Open the Inspector Window, press on the "Test" GameObject in the Hierarchy
4. Play the Scene, scroll up and down quickly in the Inspector Window

Expected result: The Editor does not worsen in performance
Actual result: The Editor visibly worsens in performance and stutters
