When you delete an element in a nested structure, you lose all selection.
This means if you want to continue working around that level, you have go dive again to that level (double-click, double click, double, click, double click…)
Deleting an element should auto select the immediate upper level to stay where we’re currently working
Or auto select the previous element in that hierarchy maybe, or the next one.
But staying around there, not going back to root level.
