[NTG-context] Bug: footnote's "textcommand" overflows?

Dear all, there appears to be a bug in the handling of font features in footnotes… the following messes up the footnote block in 2011.04.20 16:23, but yields the expected result in 2011.02.14 23:30. --- \definefontfeature [superscripts] [default] [sups=yes] \usetypefile [type-optical] \usetypescript [minion] \setupbodyfont [minion] \setupnote [footnote] [textcommand=\setfontfeature{superscripts}, textstyle=, numbercommand=] \starttext \dorecurse{9}{This\footnote{Hello World #1} is a test.\par } \stoptext --- The problem is not triggered for Latin Modern, also not for, say, "textcommand=\it". What's going on? Best, Oliver
