Generated Doc of functors doesn't include template parameters

Currently, the generated doc doesn't include any mention of potential template parameters of a functor. E.g:

But it's defined as:

DOCA = Functor(
    'DOCA',
    "Combination::DistanceOfClosestApproach",
    "Combination.h",
    """Compute the distance of closest approach between two 'states'.""",
    Params=[('Child1',
             'Index [starting from 1] of the first child to consider.', int),
            ('Child2',
             'Index [starting from 1] of the second child to consider.', int)],
    TemplateParams=[('DistanceCalculator',
                     'Distance calculator implementation to use.')],
    AllowMultiplePositionalArguments=True)

I guess this would be a WP3 thing, but I'm not sure who the best person is, to ping for this functor stuff 🤔 maybe @mvesteri @poluekt can point me in the right direction?
