> Related to LUCENE-9400, tessellator might fail when several polygons are connected to the same polygon vertex, and this vertex is connected from more than one segment. For example the following polygon:
>  
> !image-2020-06-25-11-03-02-075.png|width=377,height=232!
>  
> Holes get connected the following way:
>  
> !image-2020-06-25-11-05-50-406.png|width=357,height=236!
>  
> Two holes are connected to the same point, and this point is shared across different segments. We need to make sure we connect in such a way that we are not crossing each other.
