Issue description

When creating a MenuBar with a PopupMenu that has prefer_native_menu=ture, the menu doesn't show in the correct location (Under the selected menu item). In the attached project it is showing above the window, in my actual application it is showing to the right of my window. I have tested all options of system_menu_id, but none seem to affect the position.

Not sure if this is related to #93622, as this happens all the time, and not just after the first time. Also this doesn't use an code.

Steps to reproduce

• Create a new scene
• Create a Node as the scene root
• Add a MenuBar as a child of the root
• Add a MenuPopup as a child of MenuBar
• Set prefer_native_menu to true on the MenuPopup in the Inspector
