Re: strange detached beam issue

[William Rehwinkel]

    It should be noted that on 2.25.7 this
      doesn't happen on my machine, and the beam renders correctly
      (after running convert-ly on your snippet, it didn't change
      anything).

I have a section of piano music where two voices start in the treble clef and subsequently move down into the bass clef. When the right hand moves down, the beam stays in the treble clef unattached to anything:

When I try to isolate this section, the problem does not occur. I am mystified as to what is going on. What might be some things I could try?

\version "2.24.1"

top = { \change Staff = "upper" \voiceTwo }
bottom = { \change Staff = "lower" \voiceOne }

  fis,4)

  \new PianoStaff {
