#1 wrong sized rubber band

[Anonymous]

in selectable.js, startDrag function line 137-138 use rubberBandContainerOffsets instead of rubberBandContainer:

wrong:

var currentX = Event.pointerX(event) - this.rubberBandContainer.offsetLeft;
var currentY = Event.pointerY(event) - this.rubberBandContainer.offsetTop;

patch:

var currentX = Event.pointerX(event) - this.rubberBandContainerOffsets.left;
var currentY = Event.pointerY(event) - this.rubberBandContainerOffsets.top;
