Description

User already has an account with email provider and try to sign in with Microsoft. The account-exists-with-different-credential exception rises but the exception does not have an email and credential property. According to the document, the exception is supposed to have the properties so user can link the existing account with Microsoft account. It works with android but does not with iOS.

Reproducing the issue

1. Sign up with email provider. => Make sure there is an account in firebase console.
2. Sign in with Microsoft with same email using below code.

final provider = OAuthProvider('microsoft.com');
// or final provider = MicrosoftAuthProvider();

provider.setCustomParameters({'prompt': 'select_account'});

UserCredential userCredential = await FirebaseAuth.instance.signInWithProvider(provider);

Expected behavior:
account-exists-with-different-credential rises and it has email and credential property.

Actual behavior:
account-exists-with-different-credential rises and it does not have email and credential property.
