[NTG-context] Strange extra space when using cases in an inner align in math

Hi, I currently have the case of a strange extra space in math mode when using cases in inner align. Here is a MWE to demonstrate the problem: ``` \definemathsimplealign[inneralign] \startdocument \startformula \startalign \NC a = b \NR \NC \NC \startinneralign[n=3,align={1:right,2:middle,3:left}] \NC A \NC = \NC B \NR \NC f(x,y) \NC = \NC \startcases \NC \text{strange} \NC a \NR \NC \text{normal} \NC b \NR \NC \text{also normal} \NC b \NR \stopcases \stopinneralign \stopalign \stopformula \stopdocument ``` "strange" and "normal" are not aligned what I would expect but strange has more space in front of it. Is this a usage error or a bug in the math engine? Best, Gerion
