I guess the reason is, that the circle with the autoscaled radius 
doesn't necessarily fit into the canvas and is cut off.

The position is correct, but I would omit the grid circle which is at 
the same radius as the polar border.

In general, if I have a polar plot with autoscaled radius I would expect 
the complete circle of radius <autoscaled r> to fit completely in the 
canvas.
This seems to me like "natural" behavior and would probably also work 
better together with positioning of the polar border.
