If I use the Vector skin and change (by user JS) the class of the element with ID "ca-watch" or "ca-unwatch", the text of the Watch/Unwatch link doesn't change when I click on it.
I think this is because Vector has additional <span> around the link text and because of this, wgAjaxWatch.setLinkText doesn't work.
