[Playable] AnimationClipPlayable's speed parameter can't be adjusted when setting speed with AnimatorControllerPlayable SetSpeed



How to reproduce:
1. Open the user's attached "" project
2. Open the "SampleScene" Scene
3. Enter Play Mode
4. Press the "SetSpeed(0.1)" button in the Game view
5. Observe the Game view

Expected result: 0.1 speed is applied to both the "Cube" and the "Capsule" GameObjects
Actual result: 0.1 speed is applied only to the "Capsule" GameObject

Reproducible with: 2018.4.30f1, 2019.4.18f1, 2020.1.17f1, 2020.2.2f1, 2021.1.0b2, 2021.2.0a1

  1. Resolution Note (fix version 2021.2):

    More info on the case to avoid confusion as to why the bug reported is not a bug, but that there was still a bug fixed.

    The expected result should not be that the cube has its speed changed. The reason being that the SetSpeed function is applied to a different playable graph than the cube animator graph. It is only applied to the cylinder playable graph.
    There was a bug, just not the one reported in the steps. Applying a set speed to the animator controller playable should affect the speed of the animation clip, which is not the case in our current build. This can be seen by changing the weight in the script component of the cylinder. When having a weight of 1, meaning the animator controller is used, applying a speed does nothing. This was fixed.

    Another info : We cannot apply a speed modifier to any child of the animator controller. They will just be ignored. The speed can only be applied to the animator controller playable.
