Karl Wright commented on LUCENE-8257:

For standard polygons, we wound up accepting the fact that points on the 
opposite sides of the world would be within the shape, and even modified the 
bounds computation to allow it.  The question is whether that is what you are 
seeing here?

> When a polygon have two consecutive points very close to each other but not 
> numerically identical, we can get wrong results because planes defining that 
> edge intersects somewhere else on the world. At that point the following 
> check is evaluated to true:
> {code:java}
> if (edge.plane.evaluateIsZero(thePointX, thePointY, thePointZ) && 
> edge.startPlane.isWithin(thePointX, thePointY, thePointZ) && 
> edge.endPlane.isWithin(thePointX, thePointY, thePointZ)) {
>   return false;
> }{code}
