In other words: the object's individual font-size property is getting

Just declare
#:properties ((font-size 0))
in order to make the current font-size available and use
(magstep font-size)
as a "fudge factor" instead of a hard-coded 1.125.
Thanks, Torsten. Based on this, I wonder if \scale would be the better
choice to avoid what happens with \magnify:
%%%%
#(define-markup-command (fontsize-x-height layout props size arg)
(number? markup?)
(let* ((y-extent (ly:stencil-extent (interpret-markup layout props
(markup "x")) Y))
(scale-factor ((lambda (x) (cons x x)) (/ size (cdr
y-extent)))))
(interpret-markup layout props #{ \markup \scale #scale-factor
#arg #})))
%%%%
