Google Calendar API - Requesting multiple scopes puts checkbox in authorization request?

I have a Google Calendar API setup with Oauth2.

I can request only the calendar scope, but I want to add the userinfo.email scope. When I add it using the setScopes() function like below the authorization request page does not automatically check the checkbox for the CALENDAR_EVENTS scope:

Only asking for CALENDAR_EVENTS scope:

$client->setScopes([Google_Service_Calendar::CALENDAR_EVENTS]);

I get an authorization request like this:

When I request both scopes:

$client->setScopes([Google_Service_Calendar::CALENDAR_EVENTS, 'https://www.googleapis.com/auth/userinfo.email']);

The user must check the calendar scope explicitly. Most users will not read and check that scope. So, I don't get the most important scope.

How to I get the CALENDAR_EVENTS scope to automatically check when requesting multiple scopes? The API is setup to allow that scope.
