Volta bracket length with grace note

Hi everyone,

I've run into a new (to me) twist on issue #34.  If you try to control the
volta bracket length and the next measure contains a grace note, the volta
bracket covers that grace note.  That is, it doesn't stop at the end of the
measure.  Most issue #34 problems I know how to solve but this one is
illuding me.

Here is a MWE and I've attached a picture of its output.

%%% Start
\version "2.26.0"

\relative {
  \repeat volta 2 {
    c'1
    \alternative {
      { c1 }
      {
        \override Score.VoltaBracket.musical-length = \musicLength 1
        c1
        \grace { c8 } c1
      }
    }
  }
}
%%% End
