Steps to reproduce:

1. Open the attached Project
2. Open Scene "Input test"
3. Select "MagePlayer" Prefab in the Hierarchy and double click the Animator Controller that's assigned to it to open it
4. Enter Play Mode, double click the Blend Tree "Locomotion Walk" and select the "Blend Tree WALK" Blend Tree State
5. In Play Mode use WASD to walk about and observe the Visual Representation of the Blend Tree Parameters and Animation Weights

Actual results: The Visual Representation is not updated, the Inspector is not repainted when the Blend Tree Parameters are updated in Play Mode. Users cannot see how the Blend Tree updates in real time unless the Inspector is repainted in other ways (e.g. Pressing Play in the Animation Preview Window in the Inspector or cursor is hovered over Inspector fields)

Expected results: When Blend Tree Parameters change in Play Mode the Blend Tree's Visual Representation updates in the Inspector

Reproducible with versions: 2022.3.66f1, 6000.0.59f1, 6000.1.17f1, 6000.2.7f1, 6000.3.0b4, 6000.4.0a1

Tested on (OS): Windows 11

Workaround for users: Play the animation preview in the Inspector so that the Inspector would repaint
