New role not available for use until role page revisited

Noticed while testing something entirely unrelated that if you create a role "roleA" save, then attempt to create another role, you'll find that "roleA" isn't available in the roles list to assign to this new role.  You first need to leave the roles page, then come back, and now the "roleA" will be available for selection in the new role's configuration

Haven't done any investigation to see if this occurs in releases prior to 3.14

Update

Also to note, this works the same in the reverse fashion.  If you delete a role, that role is still available to be assigned to other roles until you revisit the role page
