[NTG-context] Footnote breaks tagging

Hi,

ConTeXt mkiv is the only TeX-based typesetting system that can produce
tagged PDFs and this is a really useful feature. Unfortunately, footnotes
seem to upset tagging. MWE:

\setuptagging[state=start]
\starttext
Text\footnote{Note}
\stoptext

In the resulting PDF, the structure tree seems okay to me, but the content
stream is defect:

0 g 0 G

Clearly, in the content (around line 10) we miss something like
/sup <</MCID 1>>BDC
I hope that this is a minor issue in the processing of footnotes. I would
very much appreciate if you could fix this bug.

Cheers,
Christoph
