Unsure what had happened in another post and poked in my instance’s main(?)/meta(?) community ([email protected]), but after a short back and forth, and seeing the behavior repeat here as well, I think the owner’s assumption is correct, the first of each pair of community links here is actually a hyperlink manually created.
