Temporary staff too long when grace notes are in the permanent staff

[Knute Snortum]

If I have a temporary staff, like an ossia, and if the next notes in
the permanent staff after a \stopStaff are grace notes, the temporary
staff extends too long, over the grace notes.  Here is a MWE and
picture attached:

%%%
\version "2.23.7"

rightHand = \relative {
  d''4 d8 b \grace { c,8[ d f] } b4 r |
}

ossia = \relative {
  \stopStaff s4 \startStaff d''16 c b8 \stopStaff s2 |
}

<<
  \new Staff \with {
    \remove "Time_signature_engraver"
    \hide Clef
    \hide KeySignature
    \magnifyStaff #2/3
  } {
    \ossia
  }
  \new Staff \rightHand
>>
%%%

Seems like a bug, or at least an "ugly."  Is there any work-around?
