Facebook 2FA Breaks Sign-In Flow in Unity WebGL #27

Hello,
I'm experiencing an issue with the Facebook authentication in a WebGL project.
The problem arises when users with Facebook's two-factor authentication (2FA) enabled attempt to log in.
When a user with 2FA enabled tries to log in, the authentication flow breaks after entering the 2FA code. Instead of redirecting back to the game, the login popup navigates to the Facebook home page. Although the game gets authorized, it doesn't receive the authentication token, and the user remains unsigned in, so repeated attemp helps but this making user expirience worse.
This issue does not occur with Facebook accounts that do not have 2FA enabled, or when user was logged in previosly,
