\fine and \section across staves

[Joel C. Salomon]

There’s a change between 2.23.6 and 2.23.80 in how `\fine` and 
`\section` appear across staves.  Below is a near-minimal cut-down 
version of my score illustrating the change, and images showing the 
difference.

I normally put commands like `\bar "||"` in a single place (a Dynamics 
section, usually) and they take effect across all staves.  And in fact, 
replacing `\section` with `\bar "||'` does take effect across all 
staves.  So I would like to not have to repeat `\fine` and `\section` also.

Was this change intended?  (I am aware of other changes to `\fine` 
between 2.23.6 and the new release candidate.)
