MouseListener on Components used in ListCellRenderer

Question

I have been trying to create to create a Custom Renderer for a ComboBox that allows me to have a clickable JLabel containing an Icon in every cell.

The Problem i am having is, that no MouseEvent seems to reach the components inside of the JList that is part of the BasicComboPopup.

This is the Component that returns the Component that should be rendered:

@Override
  public Component getListCellRendererComponent( final JList<? extends E> list, final @Nullable E value, final int index,
                                                 final boolean isSelected, final boolean cellHasFocus )
  {
    final Component plafComponent = plafRenderer.getListCellRendererComponent( list, value, index, isSelected, cellHasFocus );

    if ( value instanceof String && value.equals( BasicComboBox.SEPARATOR ) )
    {
      return new JSeparator( SwingConstants.HORIZONTAL );
    }

    final JPanel panel = new JPanel( new MigLayout( new LC().fill().flowX().insetsAll( "0" ) ) );

    final Optional<JLabel> cast = Optionals.cast( plafComponent, JLabel.class );
    cast.ifPresent( label ->
    {
      label.setText( converter.apply( value ) );
      panel.add( label, new CC().growX().pushX() );
      panel.setBackground( label.getBackground() );
    } );

    if ( decideIfShowIcon.apply( value ) )
    {
      final IconLabelWithAction<E> iconLabel = new IconLabelWithAction<>( icon, onClickIconConsumer, value );
      panel.add( iconLabel, new CC().alignX( "center" ).gapRight( "5" ) );

      iconLabel.addMouseListener( new MouseAdapter()
      {
        @Override
        public void mouseReleased( final MouseEvent e )
        {
          System.out.println( "Never happens" );
        }
      } );
    }

    return panel;
  }

Drawing the icons works fine, they are just not clickable, I am uncertain why.

I have also tried catching the events on the JList, not even that worked.
