Missing volta bracket in 2.8.0

[Shamus]

I don't know if this has been pointed out already but it seems that
\stopStaff followed by a \startStaff causes volta brackets to disappear.
I also don't have the foggiest idea how to fix this either.

\version "2.8.2"
\score
{
\relative c'
<<
\new Staff
{
\override Staff.TimeSignature #'style = #'()
\time 4/4
c4 d e f |

\repeat volta 4 { c4 d e f | f e d c | c d e f | }
\alternative { { f d e c | } { f e d c | } }

c4 d e f | \stopStaff s1 \startStaff | c4 d e f |

\repeat volta 4 { c4 d e f | f e d c | c d e f | }
\alternative { { f d e c | } { f e d c | } }

c4 d e f |
}
