Well, actually window.addEventListener() really does need to be connected to immediately. So I came up with this:

    init() {
        let id = setInterval(() => {
            if (PDFViewerApplication.initialized) {
                this.overrideSettings();
                PDFViewerApplication.eventBus.on("pagesinit", () => {
                    this.autoResize();
                });
                clearInterval(id);
            }
        }, 200);

That seems to work properly.
