Reproduction steps:
1. Open the user's attached project "VolumeComponentEditorTest.zip"
2. In the Project window go to the Assets folder and select the ScriptableObject "TestVolumeProfile.asset"
3. Expand "Test Volume Component" in the Inspector window

Expected result: "Test Volume Component" parameters are placed in the sections from the TestVolumeComponent.cs script
Actual result: "Test Volume Component" parameters are not placed in the sections from to the TestVolumeComponent.cs script

Reproducible with: 9.0.0-preview.35 (2020.1.17f1), 10.2.2 (2020.2.0b14, 2021.1.0a9)
Not reproducible with: 7.5.2 (2019.4.16f1), 9.0.0-preview.13 (2020.1.17f1)
Could not test with: 2018.4.30f1 (Associated scripts could not be loaded)

Note:
- When updating the package version to 9.0.0-preview.35 a new line "m_Parameters.Sort(new ParameterSorter());" appears in the VolumeComponentEditor.cs script, which causes the issue by making the parameters ignore the placement order which is written in the TestVolumeComponent.cs script. If the line is commented out, the issue disappears and the parameters are placed in the order which is written in the TestVolumeComponent.cs script
