Making the top staff invisible, in a part, will make all system-wide elements invisible

Issue type

Engraving bug (incorrect score rendering)

Bug description

I checked; this doesn't happen with the main score, it is exclusive to parts. It is worth noting, however, that clicking the items in the timeline will select them and place the "playhead" at them, but will NOT move the screen to them as it normally does.
I wonder if this might be related to the known "things missing from parts" bug.

Steps to reproduce

1. create a score with three instruments (I don't know how partmaking would interact with making a part that has as many staves as the main score)
2. place a few items like tempo text and rehearsal marks that apply to the whole system
3. create a part that includes any two instruments
4. hide the first instrument from the properties panel
   You will notice that all the system-wide items are hidden, and clicking them through the timeline will not make them appear or move the screen to them. It will, however, move the playhead to them, meaning that pressing play will make the playback begin at the point of the clicked item.
