The #contentSub element is always present, but does not have any content most of the times. Consequences: 1) The Monobook and Vector skins do #contentSub { margin: 0 0 1.4em 1em; }, which causes 1.4em extra whitespace between page title and first paragraph (similar issue as bug 19567). 2) In Vector, absolute-positioned elements are relative to #bodyContent (r52855), whose first child is #contentSub (first visible child actually, given that #siteSub is not displayed by default). The fact that #contentSub is always present and always has a bottom margin, but does not always have content causes the content edge of #bodyContent (and, consequently, its absolute-positioned descendants) to be unstable. Compare the position of the coordinates at [[de:Athen]] (empty #contentSub, coordinates below header line) with [[de:Athina]] (non-empty #contentSub, coordinates above header line).
