What the issue is

Links that do not notify the user of a change in context, such as opening a new window or tab, or causing a document to unexpectedly download, navigating away from the current page, or triggering a significant change on the current page without prior warning. may disorient users when the context changes unexpectedly, not knowing if the action took them to a new page, opened a new window, or made changes without their knowledge.
