Controls not working with mock sync?

[niksite]

When using a real connection, controls=[('2.16.840.1.113719.1.27.103.7', True, 'sn')] works perfectly. However, when using client_strategy=MOCK_SYNC, I am encountering the following error:

control = ('2.16.840.1.113719.1.27.103.7', True, 'sn')

    @staticmethod
    def decode_control(control):
        """
        decode control, return a 2-element tuple where the first element is the control oid
        and the second element is a dictionary with description (from Oids), criticality and decoded control value
        """
>       control_type = str(control['controlType'])
E       TypeError: tuple indices must be integers or slices, not str

.direnv/python-3.9/lib/python3.9/site-packages/ldap3/strategy/base.py:580: TypeError

It seems that the controls in the case of MOCK_SYNC are not passed through build_control or something?
