[NTG-context] linenumbering and text backgrounds

Hi, Line numbering does not work well with text backgrounds (with location=paragraph). Consider the following minimal example \definetextbackground [test] [location=paragraph, alternative=0, frame=off, background=color, backgroundcolor=yellow] \starttext \startlinenumbering \starttest \dorecurse{20}{some random text} \stoptest \dorecurse{20}{continue text} \stoplinenumbering \stoptext Notice that line numbers 1 and 2 are overprinted, and so are 6 and 7. I can "fix" this by using "location=text", but that only highlights half of the last line (while I want full line to be highlighted). Any idea on how to fix this? Thanks, Aditya
