[NTG-context] MKIV bug

Hi, Hans Using context=experimental, the following cross references all appear as ?? MKII works fine. \placeformula \startformula \startalign \NC v \NC = u + at \NR[eq:v] \NC h \NC = ut + \frac12 gt^2 \NR[eq:h] \stopalign \stopformula Equation (\in[eq:v]) tells the final velocity after time $t$ and equation (\in[eq:h]) tells the distance travelled in time $t$.
