hasROLE(rolename) function always returns false

Given teiid-security-roles.properties contains user=NoRolesRole and the VDB in use has data roles defined, when logged into Teiid as user, the following SQL should return true.

SELECT hasROLE('NoRolesRole')

However, it always-AFAICT-returns false.

(Roles are working for this VDB as this user is not able to query certain tables.)
