[NTG-context] --extra=select --once in LMTX

Dear list, I think there is a bug in LMTX with: context --extra=select --selection=15:30 a.pdf --once This gives 16 repetitions of page 30 (with any PDF document). If --once isn’t used or MkIV is deployed, selection is fine. Could anyone confirm the issue? Many thanks for your help, Pablo -- http://www.ousia.tk
