For stem up, we use the width of a quarter noteheadto shift the stem right without considering the current notehead glyphs (note the "s", for chord, it's not a trivial case..., I guess notehead should be right aligned in this case...)

It's in chord::stemPosX() https://github.com/musescore/MuseScore/blob/72950fca7a87ceeb45e9484b991…

We use noteheadWidth https://github.com/musescore/MuseScore/blob/72950fca7a87ceeb45e9484b991…
call score->notehead() which is set here:
