OAuth2 consent page ignores Accept-Language

[tsujiguchitky]

Description

When OpenAM works as OAuth authorization server, you start authorization code flow, then the consent page is displayed after authentication. This consent screen seems to ignore the browser locale. Even if you deploy translation.json corresponding to the browser locale, it will be displayed in English.

However, it seems that the OpenID Connect ui_locales parameter is supported.

Steps to reproduce

1. Configure OpenAM as OAuth Authorization Server
2. Register the OAuth Client
3. Set the locale of the browser to Japanese
4. Start authorization code flow
5. Log in as a user
6. Check locale when the consent page is displayed

Expected Results

The consent page is displayed in Japanese.

Actual Results

The consent page is displayed in English.
