Description
I'm trying to calculate the difference of two valid geometries and getting an invalid one back. The input geometries both have integer coordinates, so I would hope that numerical precision isn't an issue. I'm not totally sure this is a bug - perhaps I've just got the wrong expectations of what should happen?
I've attached a test case, which I've tested against both 3.5.0-1ubuntu2 (on xenial) and latest master (3.6.0dev-CAPI-1.10.0 r4257) with the same results.

See JTS issue https://github.com/locationtech/jts/issues/255
This is likely due to a logic error in the polygon building phase of overlay.
