simulator is stuck before calling GlanceView.onLayout on devices with liveUpdate

Similar to https://forums.garmin.com/developer/connect-iq/i/bug-reports/simulator-doesn-t-call-glanceview-onupdate-even-though-more-than-30-seconds-passed-since-app-was-stopped (which is a similar bug on sim on devices without liveUpdate)

For devices with liveUpdate, it works for the 1st time in the sim, but then when restarting the app it's usually stuck: it calls initialize but onLayout, onUpdate are never called (not even after 10 minutes), and in this case we either see a blank white screen or the black screen with the CIQ triangle (as we saw when the app was stopped).

The code is the same:

import Toybox.Graphics;
import Toybox.Lang;
import Toybox.WatchUi;

(:glance)
class WidgetGlanceView extends WatchUi.GlanceView {
    const TIME_FORMAT = "$3$:$4$:$5$";

    public function initialize() {
        log("g.initialize");
        GlanceView.initialize();
    }

    public function onLayout(dc as Dc) as Void {
        log("g.onLayout");
    }

    public function onShow() as Void {
        log("g.onShow");
    }

    public function onHide() as Void {
        log("g.onHide");
    }

    public function onUpdate(dc as Dc) as Void {
        log("g.onUpdate");
        var text = formatTimestamp(TIME_FORMAT, null);

        var width = dc.getWidth();
        var height = dc.getHeight();
        var font = Graphics.FONT_GLANCE;
        var justification = Graphics.TEXT_JUSTIFY_CENTER | Graphics.TEXT_JUSTIFY_VCENTER;
        dc.setColor(Graphics.COLOR_WHITE, Graphics.COLOR_BLACK);
        dc.clear();
        dc.drawText(width/2, height/2, font, text, justification);
    }

    function formatTimestamp(format as String, ts as Number?) as String {
        var m = ts != null ? new Time.Moment(ts) : Time.now();
        var t = Time.Gregorian.info(m, Time.FORMAT_SHORT);
        return Lang.format(
            format,
            [
                (t.month as Number).format("%02d"),  // depends on FORMAT_SHORT
                t.day,
                t.hour.format("%02d"),
                t.min.format("%02d"),
                t.sec.format("%02d"),
            ]);
    }

}

SDK: 4.1.4, device: fenix6xpro

Output after restarting the app:
