Braces over systems where \stopStaff is active go missing

[Richard Shann]

If I use \stopStaff then systems where it is active don't display
braces, even though they do display the initial clef.
For example:

\version "2.24"
\score {
         \new StaffGroup <<
                        \new Staff  {\stopStaff c'1 }
                        \new Staff {c'1 }
                         >>
       }

Is there a way to get the braces to show?
