Describe the bug

In the Role-based policy creation form, when you hover of the helper (?) icon next to Roles, you just get policyRolesHelp

Should be a description like:
Click on 'Add roles' to include accepted roles for this policy. Checking off the 'required field' checkbox on a role indicates that that selected role MUST be present while evaluating policy, regardless of other roles. Leaving all relevant roles for the policy unchecked likes the equivalent of setting a decision strategy of 'Affirmative'
