let me be fast in providing an easier solution (I bet WS would correct
me otherwise):

\defineframed
   [vertical]
   [offset=none,
    align=flushleft,
    anchoring=left,
    foregroundstyle={\MyFont\setupinterlinespace[40pt]}]

\startframed[vertical]
     ᠣᠢᠷ᠎ᠠ ᠵᠢᠨ ᠡᠳᠦᠷ᠂ ᠦᠪᠦᠷ ᠮᠣᠩᠭᠣᠯ ᠦᠨ ᠰᠢᠯᠢ ᠵᠢᠨ ᠭᠣᠣᠯ ᠠᠢᠮᠠᠭ ᠦᠨ ᠰᠢᠯᠣᠭᠣᠨ ᠬᠦᠬᠡ

ᠰᠢᠳᠬᠡᠭᠰᠡᠨ ᠪᠠᠢᠨ᠎ᠠ᠃
\stopframed

I realized that I already added the anchoring features long ago ...
