Shape measurement or Transfer panel measurement, which is accurate?
While working today I noticed something I never quite noticed before.
1. Using the shape tool I entered precise dimension for a rectangle.

2. Upon hitting enter I noticed the dimensions of the shape and the dimensions shown in the transform panel don't mirror one another.

3. Upon changing the dimensions in the transform panel, the dimensions of the shape are no longer the same.

Is this a bug? Has it always been this way and why? Why aren't the dimensions the same for both?
