Visually it appears to me that the height should be rounded up here. In the MWE I added a \vrule to show that the determined height of the line definitely does not coincide with what one would expect.

Dear Wolfgang,

thanks again, this solution works nicely for me.  However, it only represents a workaround.  Do you think it is possible to patch it somehow in the core?  Perhaps the definition of the mathmatrix has to be adjusted somehow (in context/base/mkiv/math-ali.mkiv).

Cheers, Henri
