Comment(by pramsey):

 I don't think we'll be able to do anything about this. Despite all the
 other ceremony around it, it comes down to a dimensional collapse problem,
 as the nearly-invalid polygon collapses during the intersection routine.
 And we don't have any general solution for that problem at the moment. So
 you'll have to fix it at the application level, maybe looking for
 incredibly-small polygons, to filter them out.
