Curve Preview window and the Particle System property curve visualization show different curves when switching between the type “Curve” and “Random Between Two Curves” and then undoing the switch

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Create a new Particle System (GameObject > Visual Effects > Particle System)
3. Select the newly created Particle System in the Hierarchy window
4. Change the Start Lifetime property type to "Curve"
5. Convert the Particle System Curves to Floating window and dock it somewhere
6. Move the Curve and observe the Start Lifetime property in the Inspector window
7. Change the Start Lifetime property to "Random Between Two Curves"
8. Repeat step 6
9. Undo twice
10. Observe the docked Floating window and the Start Lifetime property in the Inspector window

Actual results: The floating window is showing "Random Between Two Curves", but the Start Lifetime property is of a "Curve"

Expected results: The floating window and the inspector are showing the same functionality
