shapeMouseEnter/Leave problems

[Seyfor]

shapeMouseEnter and Leave events are sometimes called, but not always. To repeat this bug, just drag mouse over squares. Sometimes it is painted and sometime it is not.

Hello,

This is an SVG-specific behavior caused by the lack of fill on these shape. It can be resolved by applying a fully transparent fill:
style: {
    fill: {
        color: "#fff",
        opacity: 0
    }
}

Same for the toggling code. Here we're using the fill(color, opacity) function:
        shapeMouseEnter: function(e) {
          e.shape.fill("#339fc3", 1);
        },
        shapeMouseLeave: function(e) {
          e.shape.fill("#fff", 0);
        }

See the updated snippet. I'll add this to the documentation for future reference.

Regards,
