meteor-roles: Roles.userIsInRole returns false in onBeforeAction

Updated to latest iron:router and latest alanning:roles and Meteor 0.9.3, and now Roles.userIsInRole does not seem to work within a route’s onBeforeAction.

this.route('admin', {
    onBeforeAction: function (pause) {
      if (!Roles.userIsInRole(Meteor.userId(), 'admin')) {
        console.log(Roles.userIsInRole(Meteor.userId(), 'admin'), Meteor.userId());
        this.redirect("home");
      }
    }
  });

I can see from the console.log that the user ID is correct, but userIsInRole is returning false. However, after it redirects, I can enter Roles.userIsInRole(Meteor.userId(), 'admin') in the browser console and it prints true.

So it seems like the roles are not being correctly determined until after onBeforeAction runs. Possibly I need to waitOn the subscription to the roles field, but I don’t think I had to do that before.
