Curious.  The skylines look interesting, almost like the SpanBar is not 
being factored in, only the parts of the BarLine.

Below, I attempted to add some virtual height to the ChordName, and it 
seemed to allow the ChordName to push the BarLine (and SpanBar) to the 
right:

%%%%
\version "2.22.0"

#(ly:set-option 'debug-skylines #t)
\layout {
   \context { \Score
     \override NonMusicalPaperColumn.stencil =
       #ly:separation-item::print
   }
   \context { \ChordNames
     \override ChordName.extra-spacing-height =
       #'(0 . 2)
   }
}

\score {
   \new GrandStaff <<
     \new Staff \relative { c''4 c c c | c c c c }
     \new ChordNames \chordmode { c2. q8. des16:maj9 | q1 }
     \new Staff { \improvisationOn b'4 4 4 8. 16~ | 4 4 4 4 }
   >>
}
%%%%

Still sounds like a defect of some sort, as the default behavior should 
probably be handling things.  But perhaps this trick above might be 
useful in whatever score you are working on as a stopgap.
