Any hint how to use wrap?

Dear Squeakers,

can anybody give me a hint how to use the 'Sketch wrap' in the
Squeakland-Squeak version 3.8-05 #556?

When an object moves beyond the limits of its container, wrap makes it
re-appear on the other side. It is as if the container is a globe.

Try dragging a playfield out of Supplies into the world and then drag a star
into this playfield. Open the viewer for the star and create the following
script and start ticking that script.
        star forward by 5.
        star wrap.

You can turn the star around to see what happens as it moves disappears out of
view in different edges.

Yes I expected that.
But it doesn't work.

Even in a newer image! (Squeak3.9-final-7067.image)

I thought, I was doing something wrong...

Is it broken?

Strange indeed. It also does not work in the OLPC Etoys image. I filed  
a bug report:

forward command will not go beyond the fence if the playfield option "fence
enabled" is set. So it will not wrap around. If you want morphs to wrap
around in a playfield, turn the fence off (see attached project).
