One way around this is to take your code and set calc: function () {return
0;} instead of returning null. Then in options I set lineWidth = 0.
Not very elegant, but it solves the problem of the area opacity sticking
around. See: http://jsfiddle.net/s8wt6/
If you have any other solutions, would love to hear them.
