Dragging a material from components view into navigator under a model binds the new material twice to the model's materials property

• Create 3D project or add a View3D to an existing project
• Drag a PrincipledMaterial from components view into the cubeModel in the navigator
• Check the code view for the cubeModel

--> The material appears twice in the materials propecty of the cubeModel

            Model {
                id: cubeModel
                source: "#Cube"
                materials: [principledMaterial,principledMaterial]
                eulerRotation.y: 45
                eulerRotation.x: 30
            }
