Animator Enum Properties get set to 0 instead of the value specified in the Scene when the Property is animated by a State that is not playing

Reproduction steps:
1. Open the user-attached "AnimatorEnumDefaultValue.zip" project
2. Open the "Assets/Scenes/SampleScene" scene
3. Select the "Cube" GameObject to open its Inspector window
4. In the "Cube (Script)" Component, take note of the "Test Enum" value
5. Press Play and observe the "Test Enum" value

Expected results: "Test Enum" value stays at "Choice 1" when Play is pressed
Actual results: "Test Enum" value changes to "Choice 0" when Play is pressed
