P: Incorrect bahavior of Warp Transformation of Smart Object when distorted past a certain degree

I believe there is a bug within the Photoshop CS6 Warp Transformation when working with Smart Objects.
In trying to warp a smart object to conform to an upward facing, slightly curved surface, the warp control handles/points respond incorrectly in reverse; moving one on the lower left outwards warps the image outwards on the upper right. All control point movements result in this backwards behavior.
