[NTG-context] Nested aligns in formulasjj

Hi, I try to typeset a nested align in a formula. However, the results looks really wrong. Here is a MWE: ``` \starttext \startformula \startalign \NC a = \NC (b, c) \quad \text{with}\NR \NC \NC \startalign \NC b \NC = something \NR \NC c \NC = someother \NR \stopalign \NR \NC somelong = \NC bla \NR \stopalign \stopformula \stoptext ``` Am I doing something wrong or are nested aligns not possible? Best, Gerion
