Motion path isAngle strange behavior

I tried to use your exemple to animate a kite but I noticed a problem, the shape seems to flip when it hit the quarter circle.

You can see it here

Indeed the value of the angle goes from -90 ° to + 90 ° instantaneously, its a bug. You can try to use this short workaround by setting the angleOffset manually:

angleOffset: function (currentAngle) {
  return currentAngle * 2;
}

Note that this will not give you exactly the desired effect.
