Pie config with size produces labels overlap on reflow

[emimuresan]

Setting both innerSize and size options in highcharts config for "pie" type chart causes a labels overlap issue when expanding the chart to a larger size, then collapsing to the original size. Depending on expanded size, labels either overlap the chart or overflow outside the container when a larger width is given.

Note: It happens regardless of innerSize.
