[NTG-context] SlideTitle font in Simpleslide module

Dear Wolfgang and Aditya,

I’d like to ask about my problems since you know well about the fonts and the simpleslide module.

I have used simpleslide module frequently without any problem,  but not in this year.

Today, I tried to make a slide using simple slide module again, but I have a problem.

First, I define Noto CJK-KR as a bodyfont.  
Korean texts in the text has no problem.
But Koreans used as a main Title and SlideTitles are not shown. The error messages are following:

fonts           > checking > char 실 (U+0C2E4) in font 'TeXGyrePagellaMath-Regular-2' with id 6: missing
fonts           > checking > char 용 (U+0C6A9) in font 'TeXGyrePagellaMath-Regular-2' with id 6: missing
fonts           > checking > char 적 (U+0C801) in font 'TeXGyrePagellaMath-Regular-2' with id 6: missing
fonts           > checking > char 수 (U+0C218) in font 'TeXGyrePagellaMath-Regular-2' with id 6: missing
fonts           > checking > char 학 (U+0D559) in font 'TeXGyrePagellaMath-Regular-2' with id 6: missing

According to this log, it look for Korean characters in the math font which fails.
If I set 

\definefont[BigFontOnehalf][NotoSansCJKkr-Bold sa 1.5]
\definefont[BigFontTwo][NotoSansCJKkr-Bold sa 2]

 
Then the following code has no problem. Of course, author, institution, and body texts are shown well as before.

\setupTitle[title={\BigFontTwo 여기에도 수학이?},
  author={정 달 영},
  institution={숭실대학교},
  date={},
  ]

\SlideTitle{\BigFontOnehalf   자주듣는 질문들}

\leftaligned{\framed[]{\tfc 수학은 왜 배우나요?}}\vfill
\midaligned{\framed[]{\tfc 수학은 누가 만들었나요?}}\vfill
\rightaligned{\framed[]{\tfc 이거 어디다 써요?}}\vfill


My question is that 
"Why it tries to use the math font for Title and SlideTitle?"

Here is a simplified example.
%font definition
\definefontfamily[notoFont][rm][Noto Serif CJK KR]
  [   it={style:regular,features:{*,slanted}},
      sl={style:regular,features:{*,slanted}},
      bi={style:bold,features:{*,slanted}},force=yes]

\definefontfamily[notoFont][ss][Noto Sans CJK KR]
  [   it={style:regular,features:{*,slanted}},
      sl={style:regular,features:{*,slanted}},
      bi={style:bold,features:{*,slanted}},force=yes]

\definefontfamily[notoFont][tt][Noto Sans Mono CJK KR]
  [   it={style:regular,features:{*,slanted}},
      sl={style:regular,features:{*,slanted}},
      bi={style:bold,features:{*,slanted}},force=yes]

%\definefontfamily[notoFont][math][Tex Gyre Termes Math]
\definefontfamily[notoFont][math][Tex Gyre Pagella Math]

\usemodule[simpleslides][style=Swoosh, font=, color=blue,]
\setupTitle[color=darkblue]
\setupbodyfont[notoFont,ss, \NormalSize]
\setuppagenumbering[state=stop]

\setupTitle[title={\BigFontTwo 여기에도 수학이? \crlf {\fancyOne Mathematics everywhere!}},
  author={정 달 영},
  institution={숭실대학교},
  date={},
  ]
  \setupfootertexts
  [\tfx FlexMath \hfill \pagenumber\ / \lastpage]
  \placeTitle

\startcomponent

\SlideTitle{\BigFontOnehalf   자주듣는 질문들}
   \null\vfill

\leftaligned{\framed[]{\tfc 수학은 왜 배우나요?}}\vfill
\midaligned{\framed[]{\tfc 수학은 누가 만들었나요?}}\vfill
\rightaligned{\framed[]{\tfc 이거 어디다 써요?}}\vfill

\stopcomponent

Hraban is the current maintainer of the simpleslides module.

You're missing the mandatory argument for \startcomponent.

1. Can you show the complete log file!

2. Does the following example work?

%%%% begin example
\definefontfamily[notoFont][rm][Noto Serif CJK KR]
   [   it={style:regular,features:{*,slanted}},
       sl={style:regular,features:{*,slanted}},
       bi={style:bold,features:{*,slanted}},force=yes]

\definefontfamily[notoFont][ss][Noto Sans CJK KR]
   [   it={style:regular,features:{*,slanted}},
       sl={style:regular,features:{*,slanted}},
       bi={style:bold,features:{*,slanted}},force=yes]

\definefontfamily[notoFont][tt][Noto Sans Mono CJK KR]
   [   it={style:regular,features:{*,slanted}},
       sl={style:regular,features:{*,slanted}},
       bi={style:bold,features:{*,slanted}},force=yes]

%\definefontfamily[notoFont][math][Tex Gyre Pagella Math]
\definetypeface[notoFont][mm][math][pagella][default]

\setupbodyfont[notoFont]

\starttext

\doloopoverlist{\rm,\ss,\tt}
   {\recursestring
    \doloopoverlist{\tf,\it,\bf,\bi}
      {\recursestring 여기에도 수학이? }\par}

\stoptext
%%%% end example
