Steps to reproduce the problem:
1. If web worker invokes `event.respondWith(fetch('https://httpbin.org/redirect-to?url=https://httpbin.org/get'))`
2. Fetch resolves via a redirection and results in a response with the final URL of 'https://httpbin.org/get'.
3. event.respondWith ignores the URL of Fetch and assigns the URL: 'https://httpbin.org/redirect-to?url=https://httpbin.org/get'.

Code: https://github.com/esanzgar/respondWith-issue

URL of the response is 'https://httpbin.org/redirect-to?url=https://httpbin.org/get'
