Resizing the pie charts when adding to a dashboard is broken

To reproduce, create a pie chart, add it to a dashboard and play a bit resizing it. There're some sizes where it goes crazy, with the div's scrollbars flickering.

It might be a bug in jquery.resize, or in flot's resize. I did a workaround a while ago by using width/height to 90%, which diminishes the issue, but it would be great to fix it for good.
