GameObjects' scaling is distorted during Play mode when their Animator component is active

How to reproduce:
1. Open the attached “IN-147920_scaling” project
2. Open the “SampleScene” scene
3. Enter Play mode
4. In the Hierarchy window, select the “Scale Here” GameObject
5. In the Inspector window, change the Transform component's Scale Y value
6. Observe the Scene view

Actual result: The “Scale Here” GameObject's scaling is distorted
Expected result: The “Scale Here” GameObject scales normally

Reproducible with: 6000.0.0f1, 6000.0.79f1, 6000.3.20f1, 6000.5.4f1, 6000.6.0b4, 6000.7.0a2

Reproducible on: macOS (M4) (26.5.2), Windows 11 (by user)
Not reproducible on: No other environments tested

Notes:

• The “Scale Here” GameObject scales normally when:
  • Scaling the “Scale Here” GameObject's root bone “CC_Base_BoneRoot” GameObject
  • The “Volwassen_Man_1” (nested under the “Scale Here” GameObject) GameObject's Animator component is disabled
