Your example is too long, I could reproduce this also with the folowing
short example.

\startquotation text \quote{text} text\stopquotation

The wrong right values did only appear if you use singlecommand
quotations within a quotation environment.

The push and popdelimitedtext macros did not work correct in this case
and ConTeXt thinks there current environment is "quotation" and not
"blockquote" when it reaches the \stopblockquote command.

A group around the single quote command helps, you core macros would
look like:


\v!margin}% \dodelimitedtextpar\dodelimitedtexttxt}}





I added in the macros above only a \bgroup in \delimitedtext and a
\egroup in every of the other three commands.
