研究方向
Review the code in FreeCAD's PartDesign module that handles Binder creation. Look for the logic that determines the parent object of the new binder, specifically when the document contains only one Body. The issue is likely in the App or Gui layer. Check the function that creates Binder and see how it selects the active body. Also consider the video evidences attached to the issue for behavior.
