The link feature between Cases and KBs is powerful, but the Search Control starts empty upon load. so if you reload a case that has a link to a KA, you won't see that KA in the search (and be granted the ability to "unlink") unless you search again for that article directly.

As such, when an KB article is linked to a Case, the Search Control should always default to show the linked articles on load.
