Query parameter in the redirect_uri is getting removed

Hi,

I am trying to authenticate a user to a web application using Azure AD. My redirect_uri for the application is something like this "http://localhost/my-app/wp-admin/options-general.php?page=mysetting".

When I request an authorization code the response is send to "http://localhost/my-app/wp-admin/options-general.php"

So the response url is like this "http://localhost/my-app/wp-admin/options-general.php?code=AA......&state=antiforgery_id&session_state=d....."

Any idea why the query parameter ( page=mysetting ) is getting removed in the response url?

Thanks,

Bibin
