Consider this input. ``` \version "2.23.81"
#(define-markup-command (strut layout props)
()
#:properties ((baseline-skip))
(ly:make-stencil ""
empty-interval
(cons (* -0.3 baseline-skip)
(* 0.7 baseline-skip))))
{
\override TextScript.show-horizontal-skylines = ##t
e'4^\markup { "a" }
e'4^\markup \concat { \strut "a" }
}
```
Why is the vertical extent of the strut ignored?
