[NTG-context] setting the space after a figure

Hello, I want to set to space between a figure (float) and the main text. I thought this worked: \setupfloat[figure][spaceafter=2cm] but it does not, while this: \setupfloat[spaceafter=2cm] works, but -- I suppose -- it does effect every float, not just figures. Here's a MWE to test it: -------------------------------------- % the next setting is consistent with my real case \setupcaption[location=top] % this works % \setupfloat[spaceafter=2cm] % this does not work \setupfloat[figure][spaceafter=2cm] \starttext \dorecurse{3}{\samplefile{lorem}\par} \placefigure[here]{}{\framed[width=\hsize,height=5cm]{}} \dorecurse{4}{\samplefile{lorem}\par} \stoptext -------------------------------------- Massi
