[NTG-context] \lfloor, \rfloor, \lceil, \rceil vanish with \big, \Big, \bigg, \Bigg and their left and right variants

Mr Hagen, is it the expected behaviour? \starttext The delimiters are correctly displayed: \startformula \left\lfloor \frac{x}{y}\right\rfloor \stopformula The delimiters vanish: \startformula \Bigl\lfloor \frac{x}{y}\Bigr\rfloor \stopformula \stoptext Maggyero

Dear NTG-ConTeXt members, The math delimiters for floor and ceiling functions (\lfloor, \rfloor, \lceil, \rceil) work with the automatic scaling commands (\left and \right) but vanish with the manual scaling commands (\big, \Big, \bigg, \Bigg, \bigl, \Bigl, \biggl, \Biggl, \bigr, \Bigr, \biggr,
