Cannot assign roles unless the User role has permission to view the Administrator role

Issue

• No new roles can be assigned if the User's View permission on the Administrator role is revoked.
  Steps to reproduce:
  1) Startup Liferay server
  2) Log in as your administrator
  3) Create a role, call it 'testRole' for example and give it the following permissions:

  Portal: View Control Panel Menu
  Users and Organizations: Access in Control Panel
  Users and Organizations: View
  Users and Organizations > Organization: View
  Users and Organizations > Organization: View Members
  Users and Organizations > User: Update
  Users and Organizations > User: View

  4) Now, under the Roles section click on the three dots next to any role (Portal content reviewer for example) -> Permissions
  Grant the 'testRole' the permissions to View and Assign members
  5) Navigate to Control panel -> Users & Organizations -> Users
  6) Create a user (testuser1) and grant them the 'testRole' and give it a password'
  7) Create another user (doesn't require a password or anything else)
  8) Log in as testuser1.
  9) Navigate to Control panel ->Users and Organizations -> Users
  Checkpoint: Notice that the user's role has been granted. Return to the Administrator user after removing it.
  10) As the administrator navigates to Control panel -> Roles
  11) Click on the 3 dots next to Administrator roles -> Permissions
  12) Revoke the View role from the default User role
  13) Now go back to the testuser1 account and try to give the Portal content reviewer to the other user
  Expected Behavior: The testuser1 is still able to grant the role
  Observed Behavior: "You do not have the required permissions" error has been seen on UI
