Can I hide RichTextItem toolbar?

I’d like to hide the toolbar of a RichTextItem widget, which is used by a DynamicForm to show HTML content. I don’t want user to change text settings, so I selected no toolbar buttons using RichTextItem.setControlGroups(“”)

But just the buttons were hidden, he toolbar gray background is still visible. Is there any way to hide it?

After its drawn call this code segment

for (int i = 0; i < e.getChildren().length; i++) {
  if (e.getChildren()[i].getID().contains("toolbar"))
    e.getChildren()[i].hide();
}

where e is the RichTextEditor
