Yeah, this problem likely stems from the substructure of the titled pane. It
has a content and title area, but no `VBox` wrapper around those that will do
correct calculations. The calculations are just done manually, and they
completely ignore many nuances of the layout system.
If `TitledPane` had been based on `VBox` it might have been easier to get
correct.
