In the latest standalone ( ConTeXt  ver: 2020.12.30 16:45 LMTX  fmt:
2020.12.30),
\startblockquote and \stopblockquote do not work when I use the key,
method=font, or include \setupquotation[method=font].

MWE
%\setupquotation[method=font]
\setupdelimitedtext[blockquote][
% method=font,
  before={\blank[small,fixed]
  \setupnarrower[left=1.5pc,right=0pc]
  \startnarrower[left,right]
\noindentation\switchtobodyfont[9pt]},
  after={\par\stopnarrower
  \blank[small,fixed]
\noindentation},]
\starttext
\input ward
\startblockquote
\input ward
\stopblockquote
\stoptext

I am attempting to get protrusion of the left double quotation mark into
the left margin when possible at the start of a line and do not
understand why my block quotations are not appearing as expected.
