The other way around, surely?

Does it where? space_glyph is initiated in init_display_interactive,
and I don't see its pixel_width changed anywhere. What do you get in
the width of that glyph in the margins?

Why not "crib" from a few lines above the code you hacked, where it
gets at the default face?
