The current article is among the suggestions without any notice that it doesn't make sense to link it. You can select it, and it is rendered as normal link (not as bolded self-link).
The current article should be excluded from the suggestions. There might be some rare occasions when you want to link the current page directly, but under normal circumstances it just doesn't make any sense.
