problem with \after on last note of DS al fine

[Kris Van Bruwaene]

I want to put a decrescendo on the last note of a DS al Fine section, but it 
generates an error message (version 2.24.3)
Example:% lily test \after with DSaF
\version "2.24.3"
music = \relative c' {
c1
\repeat segno 2
{
c1
\volta 2 \fine
c1\> \after 1 \!
}
}
