Method:

2) bar 4, bass clef - enter 2 quavers, bass clef,
3) bar 4 - move second quaver up to treble clef
4) bar 3 - add page break after
5) bar 2, bass clef - select rest in bass clef and convert to triplet
Result: beam in bar 4 vanishes

Sample score at https://musescore.com/user/788211/scores/6519271/s/uo6wDf
Came up on Telegram in https://t.me/OpenScore_Lieder_Corpus/1306 ff.
Here is the resulting file. Note that it displays correctly when loaded, but the beam in bar 4 vanishes if the triplet in bar2 is deleted or recreated

Relates to #285233: [EPIC] Cross-staff notation issues
See also #301788: missing beam in cross staff notation - could be a duplicate, but not necessarily.
It is not just the beams, the notes move sideways
Changing this issue from Once to Many, because the problem has also been seen on other scores by several reviewers of Lieder Corpus songs. Examples: @DanielR, @ashmoggs.
Boulton Harold - 12 New Songs No.7 - A Song of the South.mscz This happens whenever cross-staff notation occurs in the first bar of a page.
1. In the example, any alteration/editing of bars 40 - 41result in the beam disappearing in bar 42. It is restored when any alteration is made in bar 42.
2. If the beam is split at the point of crossing to the upper staff, the phenomenon does not occur.
3. After much experimentation I have failed to reproduce this in any bars other than the first bar on a page. eg bars 44 and 45 remain constant.
