Description
At the Loading Signed Exchanges spec, the service worker interaction is defined such that respondWith(fetch(event.request)) produces different behavior than not calling respondWith().
I'm know we've historically tried to keep this the same. Are there any other known cases where these differ?
I've also filed https://github.com/WICG/webpackage/issues/409 for the specific issue of SXG and service worker interaction.
