[Animation rigging] Two Bone IK Constraint's Target position is reset when Playables.PlayableExtensions.ConnectInput is called

Package: Animation Rigging

-

How to reproduce:
1. Open the attached project's Scene labeled "SampleScene"
2. Enter the Play Mode
3. In the Hierarchy, select the "Target" GameObject
4. In the Scene View, move the GameObject to a new position
5. In the Game View, press the "Space" key

Expected result: Two Bone IK Constraint's Target position is not reset when Playables.PlayableExtensions.ConnectInput is called
Actual result: Two Bone IK Constraint's Target position is reset when Playables.PlayableExtensions.ConnectInput is called

Reproducible with: 2019.4.0f1, 2020.1.0b12, 2020.2.0a12 (0.2.1-preview, 0.3.3-preview)
Couldn't test with Unity: 2018.4.23f1 (Package is not available)
Couldn't test with Packages: 0.1.2-preview, 0.1.4-preview (Cannot move the Target GameObject)

  1. Resolution Note:

    When changing the topology of a playable graph, the animator performs a rebind which sets all transforms back to default values. In this case, the effector targets are part of the animator's hierarchy and are therefore reset to the default position.

    To achieve the desired result, restore the transform of the effectors back after changing the topology, or else remove the effector targets from the animator's hierarchy.
