Another case of “temporary staff not ending”

[Jean Abou Samra]

I believe this exhibits a bug:

\version "2.23.14"

{
  \new Staff { c'1 }
  \new Devnull { s1 }
}


I would have expected the staff to stop after one measure.

Does anyone see a reason for this behavior being correct,
or am I right that it is another bug similar to the “temporary
staff not ending” bug fixed by Dan in 74af697126?

Thanks,
Jean
