The fixes include - detect when finding the active top loops between two possible answers - preflight chasing winding to ensure answer is consistent - binary search more often when quadratic intersection fails - add more failure paths when an intersect is missed While this fixes the chrome bug, reenabling path ops in svg should be deferred until additional fixes are landed.
