Here are two links that (due to their parent divs' limited width) split over two lines:

Random start link.
This is a long bla bla bla fragmented link. Hey previously unreachable.
AnotherA random link
B

This is a short bla bla fragmented liiiiiink. Hey now reachable.
AnotherC random link
D
Random end link.

The yellow background highlights a fragmented link's bounding box.
This bounding box covers another link. Here we test that SpatNav can reach that link.

Manual test instruction: Ensure that all links are reachable.

Also, when holding one of the four directional keys, ensure that the page is fully scrolled in that direction. Especially, ensure that focus does not get stuck inside the fragmented link's bounding box.
