Incorrect operation of the SkeletonIk3d when changing the size of all bones.

IGA22

I attached the Skeleton3d to a bone that controls inverse kinematics to control it in the editor. (IK_controller_1 > Bone_3)
And then I found that if you change the size of the bones Skeleton3d it starts to work incorrectly.
Perhaps this is a bug?

I have attached the project file.

With the IK work I’ve done, scaling bones causes all sorts of issues with IK algorithms. For the SkeletonIK, it is likely it is not measuring the bone lengths when the scale changes and so it uses the non-scaled size. It is probably a bug but it might not be easily fixable (at least from my experience - which to be fair is a bit rusty with IK)
