      When passing a c++ model to qml and attempting to use it with a combobox defined in a custom object, the popup of the custom combobox does not show the model's items correctly.

      The custom combobox works as expected with models natively defined within qml, and the c++ model works as expected with non-custom comboboxes.

      See attached project.

      QML debugging is enabled. Only use this in a safe environment.
      Binding on indicator is not deferred as requested by the DeferredPropertyNames class info because one or more of its sub-objects contain an id.
