Description

Currently when a service worker fails to start, the result is a network error. A service worker failing to start can happen due to a bad script or other non-transient errors, so it would be more useful for the user to have a fallback that bypasses the service worker in this case.

Research direction

No source file, test, or entry point is identified in the issue. Start by reading the issue and its seven-comment discussion to determine the intended fallback semantics and where the Service Worker specification should define them; done means an agreed, testable behavior for start failures rather than a network error.
