If it's not one thing, it's another ... The popup message is now visible no
matter where in a page the wikitext is being entered. So that's progress.
The popup is still too inconspicuous for my tastes (and a great opportunity for
A/B testing), but that's not what I'm posting about. My concern is with the
link that the popup message includes (the label is "wikitext"; the target is
[[Help:Wiki markup]]). If that link is clicked, the system asks the user
whether he/she wants to leave the editing page. That's a bit user-unfriendly.
I realize that smarter users can right-click and then open the link in either
another tab or a new page, avoiding the question of whether they want to leave
their editing session. But if we're aiming at the average user, it would be
great if this link were pre-defined as opening another window, so that a simple
click on the link didn't result in a perturbed user.
