Importing .qdsbundle from Navigator does not work

Steps to reproduce:

• Have some 3D model and material already exported as .qdsbundle
• Create a 3D project
• Right click e.g. on top of "scene" in Navigator
• Choose "Import component" and try importing both 3D model and material
• -> 3D model is not added to Navigator or scene, material is not added to Material Browser
• Importing .qdsbundle from 3D view, Content Library/User assets and Material Browser seems to work.
• Not 100% sure when this broke, but at least in snapshot from August 28th it was still working correctly.
