• Create 3D project
• Import a 3D model
• Add imported model to the scene
• Move the model/3D edit camera so that nothing else in the scene overlaps the imported model
• Click eyeball on the model node to hide it from 3D editor
• Click on 3D editor where the model would be

--> A selection box is displayed briefly for the model and then vanished. Click and drag can even be used to move the node in the editor, but the move is not reflected back to the creator side (not reflecting the move is correct, as there is no such node there).

The same happens for Repeater3D created models if Repeater3D is hidden with eyeball. Basically any non-instance object in the scene does this if their instance parent is hidden with eyeball.

If the same instance is hidden with visibility property, then selection works as if the node was visible. This doesn't happen on Qt5 projects, so it's a regression.

Fixing these issues may need fix on QtQuick3D side as "editor pickable" is handled there.
