Automatic barline misplaced?

[Mungo Carstairs]

I noticed that at
https://en.wikipedia.org/w/index.php?title=Symphony_No._5_(Sibelius), the
first musical example has the last barline after 9 quavers, when it should
be after 12 (time signature being 12/8).

<score sound="1"> \relative c' { \clef treble \key ees \major \time 12/8
\tempo "Tempo molto moderato" \partial 8*5 bes4~\p\<( bes2.~ | bes4 ees8 f)
bes4-- g-- ees8 f4.\fermata } </score>

I thought I might have a go at correcting it myself, despite knowing
nothing (until today) about Lilypond. However I can see nothing in the
markup that places the barline explicitly, so (with all due diffidence)
wonder whether it is a bug. I did search GitLab for open issues without
finding anything that seemed to match.

Thanks,

Mungo
