Load VE. Say "Foobar" is the first word on the page.
If you click on the link tool, by mistake or not, without selecting anything before, Foobar will automatically become a link to the Foobar page (it doesn't help that pressing ESC doesn't abort the action, the link gets applied anyway, as we know).
NicoV noticed this in several French articles, where you can quite tell links happened "by mistake" since the first word is an article, "le".
