For the make single user operation to work we expect a parent of the datablock to be around. However this is often not the case when not accessing the data from Scenes or Viewlayer display modes. For now we simply not show them in the other cases. They can be added later though, by testing the outliner tree parent compatibility with the expected parent id.
