[NTG-context] Bug in inframed

I found the following bug in \inframed, getting problems with inframing arabic words, try the following example \definefont[arab][name:arial*arabic at 18pt] \define[1]\awort{{\hbox{\setupalign[r2l]\arab#1}}} \starttext \awort{بِالصَّالِحِينَ}\blank \awort{\inframed{بِالصَّالِحِينَ}} \stoptext You see the difference: The inframed has right-shifted vocalizations. Is that easy to fix? Huseyin
