[NTG-context] Bug in alignment with LMTX version 2022.01.15 17:32

[Otared Kavian]

Hi Hans and Aditya,

Thanks for the clarification. Since for some documents I still use mkiv, I ended up using a definition which depends on whether one is using mkiv or lmtx, as in the example below. I wonder if there is a better solution.

Best regards: Otared
