Bug HumanAnimationStreamFeet IK Goal Weight Not Blending with Playable FootIK

When setting a humanoid IK goal and weight through the HumanAnimationStream, the weight is not blended correctly when animator.

The issue is that the goal position of the previous frame is taken for the blended position of the new frame, rather than the animated position, as the playable Feet IK is set to the goal position regardless of weight.

It's noteworthy that this does _not_ happen in OnAnimatorIK using the

Code (CSharp):

1. animator.SetIKPositionWeight

API - it only occurs in Animation Jobs.

EDIT: I found a workable solution, posted here: Humanoid IK in Playables
