The enabled/disabled state of the ui does not propagate to the widgets inside the tabs

[stfnp]

Disclaimer: I'm not entirely sure if this is a bug or actually the desired behaviour.

I was looking for a way to disable the entire ui, including all tabs and their contents. So I tried setting the ui to disabled before passing it to the DockArea:

    CentralPanel::default()
        .show(ctx, |ui| {
            // Set disabled
            ui.set_enabled(false);
        
            // Show dock area
            DockArea::new(&mut self.tree)
                .show_inside(ui, &mut self.context);
        });

This causes all tabs inside the dock area to be disabled, as expected. But any content of the tabs, like buttons, sliders, etc. still stays interactive. In egui itself the enabled/disabled state seems to propagate down to any sub-ui, so it might be consistent for egui_dock to also behave like this.
