Stems wrong direction when change staff is first

[Knute Snortum]

I have found what I believe is a new bug.  If you have a PianoStaff and the
right hand's notes are first in the bottom staff, the stems go down and
merge with the left hand.  Here is my MWE which will maybe clear things
up.  I've attached the output.

\version "2.25.2"

\score {
  \new PianoStaff <<
    \new Staff = "upper" \relative {
      \voiceOne
      \change Staff = "lower"
      g8[
      \change Staff = "upper"
      g']
    }
    \new Staff = "lower" \relative {
      \clef bass
      \voiceFour
      c8[ c']
    }
  >>
}
