• [x] Are you reporting to the correct repository (magic-sdk)?

🐛 Description

A promise returned from oauth.loginWithRedirect() method is returned too early before the redirect actually happens.

🧩 Steps to Reproduce

1. Have one of OAuth providers enabled
2. execute oauth.loginWithRedirect() and wait for result

🤔 Expected behavior

The promise from oauth.loginWithRedirect() should resolve just as redirect happens (or after, but not far before the redirect happens).

😮 Actual behavior

The promise resolves in about 100ms, but the redirect happens for, at least, 1 second after the promise resolves. It breaks the UI if we rely on this promise and we need to do hacks to lengthen it to last until the redirect.
