[NTG-context] Vertical alignment in Natural tables

Hi, How do I set the vertical alignment of cells in natural tables? I remember that \setupTABLE[align={middle,middle}] used to set center align vertically and horizontally. Currently, \setupTABLE[align={middle,high}] and \setupTABLE[align={middle,low}] work as expected, but \setupTABLE[align={middle,middle}] does not work. I also tried \setupTABLE[location={low}] (or lohi, or middle), but the calculation of height is wrong in those cases. Minimal example: \startsetups table \setupTABLE[align={middle,middle}] \stopsetups \starttext \startTABLE[setups=table] \NC Ward \NC \input ward \endgraf \NC \NR \stopTABLE \stoptext Aditya
