Fix for IKNINJA-1615: Enable mouse up event on top of the user document scrollbar

Chrome has a bug where mouse up does not fire when the mouse is released on top of a scrollbar. To work around this issue, I temporary increase the canvas to cover the scrollbar when drawing and then shrink it back on mouse up.
