When two rendered links are adjacent, such as [a](https://a)[b](https://b), the first
link's inclusive end equals the second link's inclusive start. Processed hit testing
maps the left half of b to that shared boundary, and this first-match search
therefore opens and highlights a; preserve the rendered link identity or otherwise
use non-overlapping hit regions.
