### Electron Version

13.1.2

### What operating system are you using?

macOS

### Operating System Version

macOS Big Sur 11.3.1

### What arch are you using?

x64

### Last Known Working Electron version

_No response_

### Expected Behavior

A registered protocol should be able to redirect to another location with the same scheme.

### Actual Behavior

When using `fetch` this results in an error about invalid URL.

### Testcase Gist URL

https://gist.github.com/dsanders11/55a1d1adc86af3c419d758027383e2cc

### Additional Information

This works when loading a window from the redirected URL, just not when using `fetch`. It appears that's because Chromium doesn't follow the redirects the same way for the navigation load, but rather starts a fresh request for the new location.
