I do not understand how x0 and y0 get turn from the rcParam names into actual values?

My guess is that this is related to the failures in the doc build

'y0': 'figure.title_y', 'ha': 'figure.title_ha',
'va': 'figure.title_va', 'rotation': 0,
'size': 'figure.titlesize', 'weight': 'figure.titleweight'}
return self._suplabels(t, info, **kwargs)
