Panel Names in ConcertinaPanel with LookAndFeel_V4

Hello

First post here. I am just a beginner with JUCE, thus my question is perhaps irrelevant.
I am working with a ConcertinaPanel (I am using the PropertiesDemo as an inspiration). And I am surprised because the names of the panels do not appear with LookAndFeel_V4.
With LookAndFeel_V3, they are visible.

When I look at the code of LookAndFeel_V4::drawConcertinaPanelHeader , I see no code for drawing a text.
In LookAndFeel_V3::drawConcertinaPanelHeader, there is a line for this :
g.drawFittedText (panel.getName(), 4, 0, area.getWidth() - 6, area.getHeight(), Justification::centredLeft, 1);

Is it a normal evolution ? Or is there something I don’t understand ???

I know that I can use my own component for the header (setCustomPanelHeader) but it is easier to be lazy !!!
