Selecting the Base Layer doesn't show its properties in the Inspector window

2) How can we reproduce it using the example you attached

1. Select any state in the Animation Controller
2. Try selecting the Base Layer (make sure it's the only layer in the controller) - the properties are not showed in the Inspector, the previously selected element is still showing instead.
3. Click on the background of the animator window - the properties of the Base Layer come up
4. If you have more layers switching between them updates the Inspector as expected.
