Limiting barline length on one-line staff?

Question

In the below example, is there any way to prevent the barline from sticking out over the 1 line staff?

\version "2.24.2"

\new PianoStaff { <<
        \new Staff \with {
                \remove Time_signature_engraver
                \hide Clef
        } {
              \override Staff.StaffSymbol.line-positions = #'(5)
              \stopStaff \override Staff.StaffSymbol.line-count = #1 \startStaff
              s1
        }
        \new Staff {
                c'1
        }
>> }

\layout {
        \context {
              \PianoStaff
              \alterBroken transparent #'(#t) SystemStartBrace
        }
}
