Layout issue with instrument names, key/time signatures and section break in a score with hidden staves

Nightly fa2e30d/ Windows 7

1) Open this new score for piano + acoustic bass: piano-bass.mscz

2) Style -> General -> Tick "Hide empty staves" -> and Untick "Don't hide empty staves in first system" -> Ok (result: the page is blank)

3) Return to Style -> General -> Tick "Don't hide empty staves in first system"

Result: the instrument names are gone to the left

4) Drag and drop a section break (Breaks & Spacers palette) in the middle of the system

Result: in the second system, instrument names to the left always, and more, Time signature and Key signature have disappeared , and so on by applying the same operation (adding section break) on this second system.

I had already noticed this issue by testing this one: #75116: Dragging breaks & spacers in an empty space in a score with hidden empty staves causes a crash

In my memory, I thought I had seen something close already. Or more and less related? But I can not find it in the former issues on the "Issue Hit List".

Perhaps it's considered as minor? Indeed, a simple Ctrl + A puts things in order. But we must do it again each time when adding section breaks. So, it's a little bit unexpected and surprising, right?
