Hi, we're looking into it and will get back to you here. Keep in mind that our online symbol/footprint renderer doesn't always render every edge case so it's best to download it and take a look in your design tool.
We looked into this. The issue isn't with the footprint. It's with the viewer. The site's preview shows the dots but once you open it in Eagle (or another tool), you'll see that it is represented accurately.
Hopefully that helps clarify. We'll add it to our roadmap to improve the viewer for this edge case your stumbled on.
