Put the rectangle inside of a masked region: <g mask="...><rect...></g> Hover the mouse around... I put the basic example here: http://codepen.io/iiroullin/pen/oWEOOM Actual results: When the mouse is moved in and out of zone triggering the transition, the rectangle occasionally erratically hops penetrating outside of the masked region Expected results: 1) The rectangle shouldn't hop 2) The rectangle shouldn't penetrate outside of the masked region
