 Now that `target="_blank"` has been removed from links in the help tab on
 pages, off-site links will take the user away from their current screen.

 While a fan of removing `_blank` links, we should set expectations for
 users, the tabs on one side open new panels, on the other side they take
 you to Codex articles on .org while still retaining a similar style.

 I can see this as being a frustrating point for users who'd use the help
 tab and suddenly find them selves not only losing data from their forms
 etc that may not be fully filled in, but also taken to a completely new
 domain.

 Introducing a new screen reader text alerting users to a link taking you
 to an external source, as well as an icon or similar for non-sr users
 would be good in regard to UX.
 I believe the link icon of a box with an arrow going diagonally out of it
 has become a well established indicator of external links, we even have a
