Kinematic rigidbody with interpolation issue

I noticed recently after upgrading to 3.5.0f5 that interpolation is causing extreme oscillation / jitter issues when animating an object that has a kinematic rigid body attached to it, with interpolation turned on. I'm animating an object using a linear iTween MoveTo.

I could be mistaken, but I thought interpolation was only calculated when a rigid body was set to non-kinematic, and is actually reacting to the physics engine. Am I right to assume that this may be a potential bug?
