wp-login.php redirect_to get param is lost during 2fa

[thomasmb]

When logging in, if the 2FA feature is used, the redirect_to part of the url is lost in the login process.

Example:

1. Open link while not logged in: /wp-admin/post.php?post=1234
2. You get sent to /wp-login.php?redirect_to=… with the original link in the url, and you log in
3. You get sent back to /wp-login.php to enter confirmation code, but now the redirect_to arg is gone from the url
4. Log in

Result: You are not sent to the original link, but instead end up at the dashboard

Any chance we can get this fixed?
