ParticleSystem.main.startSizeMultiplier doesn't scale ParticleSystem.main.startSize
How to reproduce:
1. Open project "case_1377646.zip"
2. Enter "SampleScene" Scene
3. Select GameObject "Particle System" from the Hierarchy
4. In the Inspector observe the "Start Size" value under the "Particle System" component
5. Observe the "Size Multiplier" value under the "New Behaviour Script" component
6. Enter Play Mode
7. In the Inspector observe the "Start Size" value under the "Particle System" component
Expected result: The "Start Size" value gets multiplied by the "Start Size" value
Actual result: The "Start Size" value is set to the "Start Size" value
Reproducible with: 2019.4.0f1, 2019.4.32f1, 2020.3.23f1, 2021.1.28f1, 2021.2.2f1, 2022.1.0a15
Note:
-When "Start Size" is set to "Random Between Two Constants" only the second value is affected by the "Start Multiplier"
-When "3D Start Size" is toggled only X value gets affected

Resolution Note:
I agree this isn't very clear (including in the docs) but it's the same value, not a separate one.
The main purpose of it is to let you scale the curve mode without assigning the entire curve.
When you are just using a constant, it's the same value.
