--- Comment #1 from Alex <vagulisal500 at gmail.com> ---
this is minimal reproducer

self.addEventListener('activate', event => {
    event.waitUntil((async () => {
        if (self.registration.navigationPreload) {
            await self.registration.navigationPreload.enable();
        }
    })());
});

self.addEventListener('fetch', (event) => {
    const request = event.request;
        event.respondWith((async () => {
            return await event.preloadResponse || await fetch(request);
    })());
});
