[NTG-context] Homogeneous captions for figures

[Renaud AUBIN]

Hi all,

I wanted to obtain to obtain an homogeneous formatting for my captions
whenever I use \placefigure or \placefloatcaption within combination, so
I've tried \setupcaption and \setupcaptions but

\starttext

\setupcaptions[align=left] % or \setupcaption[figure][align=left]

\startuseMPgraphic{dummy}
  numeric u; u := 5cm;
  draw origin--(1u,1u);
  draw (0,1u)--(1u,0);
\stopuseMPgraphic

\placefigure[here]{A \dorecurse{20}{very\ } long
caption}{\useMPgraphic{dummy}}

\startbuffer
  \startcombination[1*2]
    {\useMPgraphic{dummy}}{\placefloatcaption[figure]{A
\dorecurse{20}{very\ } long caption}}
    {\useMPgraphic{dummy}}{\placefloatcaption[figure]{A
\dorecurse{20}{very\ } long caption}}
  \stopcombination
\stopbuffer

\placefigure[page]{none}{\getbuffer}

\stoptext

leads to

Bug ? BTW, I need a quick solution for my PhD dissertation... so any
suggestions are welcome. I've also tried \setupcombinations with various
align values but failed to find a good solution... I use ConTeXt ver:
