If you try to add a flag tooltip for an interactive piechart diagram such as http://jsfiddle.net/85VtZ/6/ using a construct like this.flag = r.popup(100, 100, this.sector.value.value || "0"); under pie.hover, you'll see that subsequent rendering of the background shape will move up by 18 pixels each time while the text shape will be positioned normally.

How can I fix that?
