Stack margin text in ConTeXt

If I try the following in ConTeXt:

``````\starttext

text text\inmargin{this is a note.} text text\inmargin{Another note.}

\input knuth

text text\inmargin[stack=yes]{this is a note.} text text\inmargin[stack=yes]{Another note.}

\input knuth

text text\inmargin[stack=yes]{this is a note. Now longer.} text text\inmargin[stack=yes]{Another note.}

\input knuth

\stoptext
``````

then it only works for short notes. For longer notes I found the suggestion to use `stack=continue`, but I could not make that work either.

So my question is: How to make it work with floating (not overlapping) text [edit: in MKIV]?

EDIT1: It only does not work in MKIV , MKII is fine

For ConTeXt MK II, add `\setupinmargin[stack=yes]` to your preamble, e.g.:

``````\setupinmargin[stack=yes]
\starttext
This is some text.\inmargin{This is in the margin.}
This is some more text.\inmargin{This text is also in the margin.}
\stoptext
``````

If you are using ConTeXt Mk IV, you may use `\margintext` in place of `\inmargin` and also add `\setupinmargin[stack=yes]` to the preamble, e.g.:
``````\setupinmargin[stack=yes]
