[NTG-context] Footnote line position

Dear All, when a single line footnote is used, the footnote divider is rendered in larger distance than for footnotes with two or more lines (I mean a gap between the line and the footnote text). Initially I though there must be an 'empty' paragraph in my footnote but looking into the source it turned out to be a false alarm as it seems to be consistent. It can be tested easily: \chapter{Chapter}Foo\footnote{Bar}. \chapter{Chapter}Foo\footnote{Bar Bar}. Is this behaviour deliberate? Thanks, Jan ConTeXt 2013.11.14 & Win 7
