[NTG-context] prevgraf change if page break occurs in a paragraph

Hello, I am aware that ConTeXt betas might use experimental luaTeX changes (I use both stable and latest and run both), just wanted to report a change in prevgraf result. Apparently with latest beta it reports the number of lines in last page of paragraph (only tested with pars on 2 pages maximum, haven’t tried longer ones). Simple MWE reproduces the case: \starttext \dorecurse{15}{ A\\ B\\ C\\ D\\ E\\ F\\ G\\ H\\ I\\ J\\ K\\ L \\M\\ N. \the\prevgraf } \stoptext Using ConTeXt online always reports « 14 » after the letters, latest ConTeXt reports different numbers if the par before it has been split in 2 pages. Thanks Joseph
