Reproduction steps:
1. Download project "New Unity Project.zip" and open in Unity
2. Open console window
3. Select Directional Light in hierarchy
4. Right click on Anchors Min X and Anchors Min Y

Expected result: all the names in console window (SerializedProperty.propertyPath) should match appropriate property names in Inspector tab (e.g. Anchors Min X = m_AnchorsMin.x)
Actual result: some names in console window do not match the property names in Inspector tab (e.g. Anchors Min Y != m_AnchorsMin)

Reproduced on: 5.6.4p3; 2017.1.2p3; 2017.2.0p3; 2017.3.0b11; 2018.1.0a6

Note:
Unity 5.6.4p3 does not show the wrong name in the console window.
The wrong name also is shown with Anchors Max Y, Pivot Y, Rotation X, Rotation Y, Rotation Z.
