updating point.sliced = false does not work

[morganfree]

Expected behaviour

point.update({sliced: false}) should work as point.slice(false)

Actual behaviour

point.update({sliced: sliced) works only when sliced is true.

Live demo with steps to reproduce

http://jsfiddle.net/kfz3zrfk/1/

1. Click on slice - slice is out
2. Click on slice - slice does not move in

The problem is with pie series' drawPoints method, L300
groupTranslation = point.sliced ? point.slicedTranslation : {};

If point.sliced is false, then groupTranslation is empty. Compare it to point.slice():
translation = sliced ? point.slicedTranslation : { translateX: 0, translateY: 0 };
