Comment:

 I spent a while debugging this issue. In the end it appears that the
 defect is caused by the integer grid snapping strategy used by the Polygon
 library. Due to this strategy inputs, that contain almost parallel lines
 within a distance of 1x1 square, may cause defects. In order to fix this
 the whole implementation of the intersection handling needs to be
 rewritten. In terms of the current implementation I am marking this as
 working as intended.
