Issue description

When a MenuBar node is in the scene tree, its childrens' names are used as button texts in the menu bar.
Renaming the MenuBar's children does not cause the scene preview to update (until an update is triggered by other means)

Steps to reproduce

1. Create a Control node
2. Add a MenuBar node as child
3. Add PopupMenu nodes as children
4. Rename those from the scene tree
