[NTG-context] Fractions and binomial inlined in text ($n \choose \frac{n}2$): Parentheses not scaled

Dear ConTeXt folks, using the following minimal example \starttext Using \type{\choose} in text $n \choose \frac{n}2$. \startformula n \choose \frac{n}2 \stopformula \CONTEXT\ \contextmark\ \contextversion\ with \texenginename\ \texengineversion \stoptext the parentheses of the binomial in the text or too short. I guess this is because the parentheses are not scaled when inlined and that this is also a TeX limitation and therefore expected? ConTEXt MKIV 2011.11.25 21:29 with LuaTeX 0.70.1 Thanks, Paul
