[voronoi] The diagram has an infinite segment that origin point inside in closed polygon.

Created a voronoi diagram for a given closed polygon. The diagram has an infinite segment(ray) that origin point inside in polygon. As far as I understand, such cases should not be for closed polygons and second point of this segment must on the perimeter. Also in this case, two segments of the diagram intersect.

Diagram (Blue segments are polygon. Black segments are primary. Green segments are secondary.):

Infinity segment (Blue segments are polygon. Infinite segment(ray) is red. Black segments are primary segments inside polygon and not touching perimeter.):

Segments intersect (Blue segments are polygon. Black segments are primary. Green segments are secondary.):

Will it fix if you rotate the polygon slightly?
I have a feeling that there are some issues with strictly vertical lines.
