Steps to reproduce:
1. Create new Unity project
2. Make sure Editor theme is set to Light
3. Create a new "Cube" GameObject (GameObject > 3d Object > Cube)
4. Open the Animation window (Window > Animation > Animation)
5. Create a new animation by pressing the "Create" button in the Animation window
6. In Animator window press “Add Property”
7. Add Transform > Position property
8. Expand the Property
9. In Position.x property press on button on the right and select “Remove properties”
10. Observe Transform Property getting deleted
11. In Animator window press “Add Property”
12. Add Box Collider > Center
13. In Center.x property press on button on the right and select “Remove property”
14. Observe “Cube : Center” Property

\\
Actual results: Inconsistent behavior between Properties deletion, removing Transform child properties, deletes entire Transform Property, meanwhile on Box Collider Property, deleting Center.x removes only child

Expected results: Consistent behavior across context menus, wither both remove selected child property or both remove the entire parent block
