Regression to QDS4.7.1

Steps to reproduce:

• Create a 3D project
• Select cube from Navigator
• Right click Default Material in Material Browser
• -> "Apply to selected (replace / add)" options are disabled, cannot be used
• Left click Default Material in Material Browser
• Right click the material
• -> now "Apply to selected.." options are enabled and can be clicked, even though no component is anymore selected. Nothing seems to happen if those are used.
