Notes before the beat in an arpegiated chord aren’t displayed at all; not even in the previous system.
What is the request, specifically?
I want this issue to be fixed, because for romantic piano music this is a nightmare. For every arpegiated chord that I need to be displayed, I need to make substitute notes (quantized notes that are muted) and hide the actual notes (in the piano part layout).
Look:
Measure 45 in the score layout is the first measure of page 12:
But the same measure in the piano part is the first in the 6th system of the page. If I don’t hide the unmuted notes in the piano part, I’ll get this:
Interestingly, if I switch the notes to the 2nd voice (the ones that are not displayed), they become visible.
EDIT: but if you close the Score Editor and reopen it, they again are not displayed.
