Hi,
ConTeXt initializes the \belowdisplayshortskip to zero point.
I believe this is wrong, it should be equal to \belowdisplayskip:
the fact that the line above the display is short shouldnt
affect the typesetting that follows the display.
For the moment, I've fixed it by:
\everydisplay {\belowdisplayshortskip=\belowdisplayskip }
