Layout::left_to_right vs right_to_layout behavior unexpected

[pozix604]

Why does the following not work when using right_to_left but does work when using left_to_right?

use eframe::egui::{self, Align, Layout};

struct MyApp {}

impl MyApp {
    fn new(cc: &eframe::CreationContext<'_>) -> Self {
        Self {}
    }
}

impl eframe::App for MyApp {
    fn update(&mut self, ctx: &egui::Context, _frame: &mut eframe::Frame) {
        egui::CentralPanel::default().show(ctx, |ui| {
            ui.with_layout(Layout::right_to_left(Align::Min), |ui| {
                ui.with_layout(Layout::top_down(Align::Min), |ui| {
                    ui.label("AAA");
                    ui.label("BBB");
                    ui.label("CCC");
                });
                ui.with_layout(Layout::top_down(Align::Min), |ui| {
                    ui.label("DDD");
                    ui.label("EEE");
                    ui.label("FFF");
                });
            });
        });
    }
}

fn main() {
    eframe::run_native(
        "My App",
        eframe::NativeOptions::default(),
        Box::new(|cc| Ok(Box::new(MyApp::new(cc)))),
    )
    .unwrap();
}

right_to_left:

left_to_right:

Made it work with Align::Max. That was unintuitive.
