To reproduce:
1. Open attached project
2. Select Assets/Editor/EasingCurves.curves
3. Click "Edit" in the inspector
4. Click on the presets at the bottom of the window
5. The curve appears in the window and can be edited
6. Click on a different preset
7. The key point dots change to show the new curve, but the actual line of the curve still shows the previous one until you modify it in any way

Note: If you press gear icon and change preset from there everything works fine

Actual result: the actual line of the curve still shows the previous one when you change preset
Expected result: When changing presets curves should change too not only key points.
