When a multi-staved score consists of just one measure, and multiple notes are selected for deletion - multiple, but not all notes, and either in a single staff or across multiple staves - the deletion causes the "This will delete all music on these staves. Do you want to remove them from the file?" nag to be presented. And in fact, only the selected notes get deleted, not the entire staff - even if "Yes" is selected in the popup - so no harm is done.
This popup should be displayed only if ALL notes in a staff are selected for deletion ... and that is the behavior if there is more than one measure.
BTW, I know there is a option for determining if the popup is displayed at all, and yes, I want the option to delete a staff by deleting all notes from it.
BTW #2, I'm running 2023.6. I haven't tried 2023.8 yet.
