We should disable this block of code by default, with a config/console var to enable it:
// Transform to Component Space
const FTransform RootToComponent = RootTransformRefPose.Inverse();
StartTransform = RootToComponent * StartTransform;
EndTransform = RootToComponent * EndTransform;
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-187265 in the post.
