[NTG-context] Nested quotation and left-hanging punctuation together?

[Tomas Hala]

Hi all,

I do not know how to activate nested quotation together with left hanging
punctuation at all levels.

%%%%%%%%%%%%%% MWE:
\setupdelimitedtext[quotation:1][method=font]    %% cmd #1
\setupdelimitedtext[quotation:2][method=font]    %% cmd #2
\setupdelimitedtext[quotation][method=font]      %% cmd #3
%%%%%%%%%%%%%%
\setupdelimitedtext[quotation:1][left={\symbol[leftquotation]},right={\symbol[rightquotation]}]
\setupdelimitedtext[quotation:2][left={\symbol[leftquote]},right={\symbol[rightquote]}]
\setupalign[hz,hanging] %normal,%nothz,nohz,
\definefontfeature[default][default][protrusion=quality,expansion=quality]

\starttext\showframe
\quotation{asdaf\quotation{asdfasfd} adfasdfasf}

\quotation{asdaf\crlf\quotation{asdfasfd} adfasdfasf}
\stoptext
%%%%%%%%%%%%%%%%

Without any command (#1--#3):
Quotation symbols are ok but without hanging.

With cmd #1:
Quotation symbols are ok but hanging is only the first level.

With cmd #2:
Quotation symbols are at both levels the same (which is wrong) and moreover hanging is only the second level.

With cmd #3:
Quotation symbols are at both levels the same (which is wrong) but both levels is hanging.

Which definition is missing or wrong?

Best wishes,

Tomáš
