Steps to reproduce the problem:
1. Perform a request (via window.fetch api)
2. Filter by XHR 
3. Request is not shown
4. OPTION request  (if any) IS shown

What is the expected behavior?
Display both XHR and Fetch requests under XHR. Maybe rename it? 
If it's not possible by some reason, allowing a new filter `type: fetch` should be possible.

What went wrong?
XHR preset filter tab does not display fetch requests (except for OPTIONS preflight)

Did this work before? No
