Successful authentication for desktop app redirects in browser do not work

### What Happened?

After successfully authenticating in Web, Web cannot redirect user successfully so authentication for desktop app is never completed.

So far behaviour exists in GitHub Desktop App and Todoist - all installed via AppCenter

### Steps to Reproduce

1. Install GitHub Desktop App
2. Launch GitHub and follow login instructions to authenticate
3. On successful authentication, redirect is issued (x-github-desktop-dev-auth://oauth...)
4. Browser is unable to handle redirect, desktop app is never authenticated

### Expected Behavior

Browser should redirect correctly and allow apps to become authenticated
