The latter. What I suggest is that zero-width/zero-height objects
*are* taken in account for computing the skylines.
What makes your (redefined) \strut not taken into account into
skylines is not just its empty X extent. You can see that it is still
not taken into account if you replace empty-interval with '(0 . 10).
That is caused by the "" stencil expression, which LilyPond never
gives skylines to -- unless it's the whole stencil: you can see
that in this example:
\version "2.23.81"
#(define-markup-command (strut layout props)
()
#:properties ((baseline-skip))
(ly:make-stencil ""
'(0 . 10)
(cons (* -0.3 baseline-skip)
(* 0.7 baseline-skip))))
{
\override TextScript.show-horizontal-skylines = ##t
\override TextScript.show-vertical-skylines = ##t
e'4^\markup { "a" }
% \strut not taken into account for vertical skylines
e'4^\markup { \strut "a" }
% Here, \strut *is* taken into account.
e'4^\markup \strut
}
It is completely unclear to me how you would take non-printing
stencils with empty extents into skylines. How should the resulting
skylines look like? If the X extent is empty-interval, why should
the vertical skyline take this stencil into account on '(0 . 0)
and not on, say, '(2 . 2)?
If you want something in the skylines, you need to tell
LilyPond how its skylines should look like, with the extents.
If \strut needs to have an empty X extent for horizontal
spacing reasons, you will need to use ly:stencil-outline.
Regarding the latter, the handling looks inconsistent. I've opened
https://gitlab.com/lilypond/lilypond/-/issues/6472 about that.
Thanks. However, I can't immediately that these two problems are
related :-)
The same happens with embedded-ps as with "" above.
