• Create new empty project
• Open code view
• Add some nonsense component manually to the scene before Button, E.g. Asdfg {}
• Open navigator 

-->There is no Asdfg node shown in the navigator, but there is an extra "Button" node. (In previous 4.7.2 release, there is Asdfg node with yellow warning triangle shown in this case.)

• Select the shown nodes one by one and see what actually gets selected in code / property view

--> Selecting first "button" node selects the button node in property view, but in code view Asdfg node is selected. Based on the order of the nodes, this should actually be the Asdfg node.

--> Selecting second "Button" node selects button node in both code and property views.

• Save the project and close QDS
• Reopen QDS and open the saved project
• Open navigator

--> Navigator now shows only valid components in it. (In previous 4.7.2 release, there is Asdfg node with yellow warning triangle shown in this case.)
