The Permissions.reassignGlobalAdmin function is supposed to only be run with the TIMELOCK_ROLE role, see onlyRole(TIMELOCK_ROLE, "Only timelock can assign roles").
However, the TIMELOCK_ROLE is not the admin of all the reassigned roles and the revokeRole(role, oldAccount) calls will fail as it requires the ADMIN_ROLE.
The idea might have been that only the TIMELOCK should be able to call this function, and usually it is also an admin, but the function strictly does not work if the caller only has the TIMELOCK roll and will revert in this case.
Maybe governance decided to remove the admin role from the Timelock, which makes it impossible to call reassignGlobalAdmin anymore as both the timelock and admin are locked out.
