[NTG-context] Difference in right justification in LMTX

Dear list. Given the following MWE (could not reproduce with smaller example). \setuppapersize[A5][A5] \definefontfeature[base][mode=node, protrusion=quality, expansion=quality] \definefontfamily[mainfont][serif][EBGaramond][features=base] \setupalign[hanging, lesshyphenation, hz] \setupbodyfont[mainfont, 9pt] \showframe \starttext les bestes/ & sus toute la terre/ & sus tout reptile qui bouge sur surete sur la {\righttoleft terre. Dieu} donc crea l'homme a son image. \stoptext I notice that LMTX seems to add some small gap at right margin in the 1st typeset line. I attach the pdf I get with luatex and lmtx. The showframe directive makes it more visible. Joseph
