I am trying to get an URL link in a textext() via METAPOST. I’ve got this before \starttext (or after, tried both):

\setupinteraction
   [state=start,
    color=blue,
    style=bold]

The intended link shows up in blue and bold, but it is not clickable.

I’ve turned ConTeXt tracing on and see this when the text is passed to METAPOST:

cld             > tex > f : 8 : picture pic; x:=1233.000; y:=913.000; w:=180.000; h:=407.000;pic := Label( w, h, (1.000,1.000,0.784), 1.0, 1.000, (0.000,0.000,0.000), 1.000, "dashed evenly", 1.000, (0.000,0.000,0.000), 1.000, "", "\definebodyfont[11pt][rm][default=Regular at 11pt]\switchtobodyfont[11pt]\setupinterlinespace[12.1pt]\framed[align=flushleft,frame=off,offset=none,width=170.000bp]{\colored[r=0.000, g=0.000, b=0.000]{\tf The elements are shown in colors where blue represents active structure, yellow behaviour, and green passive structure.

The red is what is being typeset, the \goto is part of that.

And later this when METAPOST passes it on to TeX via textext(): 

cld             > tex > f : 8 : \definebodyfont [11pt][rm][default=Regular at 11pt]\switchtobodyfont [11pt]\setupinterlinespace [12.1pt]\framed [align=flushleft,frame=off,offset=none,width=170.000bp]{\colored [r=0.000, g=0.000, b=0.000]{\tf The elements are shown in colors where blue represents active structure, yellow behaviour, and green passive structure.

Still correct. But the end result doesn’t have a working hyperlink. Outside the route to METAPOST, the \goto statement does produce a working link.

Should this work when passed via textext()?
