Broken hover on rect

[verdie-g]

It looks like the hover on rect is not working properly. On http://martinspier.io/d3-flame-graph/ for example:

Here the mouse is on the rect but the CSS for the hover is not triggered.

Here the mouse is on a side of the rect and the CSS is applied.

I think the reason is that the <foreignObject> is hiding the <rect> in the <g>. A fix could be to swap the foreignObject with the rect in the g.
