Comment:
SIXEL support was changed multiple time in vte3 and demned unstable by vte themselves https://gitlab.gnome.org/GNOME/vte/-/issues/253,
They eventually removed sixel support in https://gitlab.gnome.org/GNOME/vte/-/commit/e264c6ed36c1a5ada131d5ee781645fff4ce9e78

So, no vte does NOT support sixel!
