Ignacio Vera commented on LUCENE-8063:
--------------------------------------
I have a closer look and it seems I am allowed to build shapes where some
points of the holes are actually outside of the shape. That is the reason it
works when I add the bounds of the holes. (The tool I am using to vizualize the
shape does not complain either so I am very puzzle, it seems valid as well)
If you get the bounds of a shape and you build the bounding box, then the shape
should be WITHIN the bounding box. In spatial3d, it can be OVERLAPS because if
the shape is touching one of the edges, it does not know if the shape is
actually crossing the edge (It would be too expensive to calculate it anyway).
So if I expand the bounding, then the relationship must be WITHIN.
Is this assumption not general?
Thanks!

> Hi [~daddywri],
> I thought it would be useful to create a random test for bounds. The test
> have shown problems with polygon with holes. In this ticket I will submit a
> random test for bounds and propose a fix for bounds for polygons.
