Facebook Social Login Provider ignores LOCALE language settings from settings dictionary

[RuchitMicro]

# Provider specific settings
SOCIALACCOUNT_PROVIDERS = {
    'facebook': {
        'METHOD': 'oauth2',
        'SDK_URL': '//connect.facebook.net/{locale}/sdk.js',
        'SCOPE': ['email', 'public_profile','ads_management'],
        'AUTH_PARAMS': {},
        'INIT_PARAMS': {'cookie': False},
        'FIELDS': [
            'id',
            'first_name',
            'last_name',
            'middle_name',
            'name',
            'name_format',
            'picture',
            'short_name',
        ],
        'EXCHANGE_TOKEN': True,
        'VERIFIED_EMAIL': False,
        'LOCALE_FUNC': lambda request: 'en_US',
        'VERSION': 'v10.0',
        'APP': {
            'client_id': '*******************',  # !!! THIS App ID
            'secret': '****************************',  # !!! THIS App Secret
            'key': ''
        }
    }
}

SOCIALACCOUNT_ADAPTER                   = "project.mysocialaccountadapter.MySocialAccountAdapter"
SOCIALACCOUNT_STORE_TOKENS              = True
ACCOUNT_AUTHENTICATED_LOGIN_REDIRECTS   = False

These are my provider settings where I have a callback function in LOCALE_FUNC returning en_US but when I login to facebook this language setting is ignored and local language is selected

Bumping this... sorry I can't provide more input but this seems valid if its still true / not already fixed. Very unlikely to be a facebook issue.
