AnimationMixerPlayable.InputWeights function does not have any impact

To reproduce:
1. Open the project “PlayablesTest”
2. Enter Play mode
3. Select the “Position” GameObject
4. In the Inspector move the "Time 1" and "Time 2" sliders to 1
5. Enable "Use Blending" to override the weights for the inputs
6. Move “Blend” slider

Expected result: The GameObject should not be in the middle because only one Animation has value 1, other has the same value as “Blend”
Actual result: The GameObject is in the middle as there is no impact of “Use Blending”

Reproducible with: 2020.3.37f1, 2021.3.6f1, 2022.1.9f1, 2022.2.0b1, 2023.1.0a2

Reproduced on: macOS Monterey 12.4

Notes:

• The script is “TestPlayables” in the Assets folder
• The function AddInput values do not override
