[NTG-context] Section head placement wrong when the after key is used

Hi! In the following example the 2nd section head stays on page one when the “after” key is used. If the blackrule is commented out the section head moves to page two as intended. What's the reason the section head stays on the previous page when the “after” is used and how to fix this? \setuphead [section] [after=\blackrule] %% works as desired when commenting this one out \starttext \startsection [title=Foo] \samplefile{knuth} \stopsection \startsection [title=Bar] \framed[height=15cm]{} \samplefile{knuth} \stopsection \stoptext Marco
