Unexpected behavior with circles

[gwpriester]

I was looking at the new Shape Tool control handles. (I would still love to be able to select any of the end points and move them with the arrow keys), and I used a circle converted to curves.

I would expect the four control points to be Smooth Joins. But they are Cusp Joins.

I select the four control points then select Smooth Join and the result was a lopsided circle.

Not of any particular value. Just interesting.
