Docstring of the `__init__` method missing in html docs

[ddundo]

For example, see https://mesh-adaptation.github.io/docs/goalie.html#goalie.mesh_seq.MeshSeq . The class docstring is present, but not the __init__ docstring. In conf.py we have "class-doc-from": "both" which should include both (see https://www.sphinx-doc.org/en/master/usage/extensions/autodoc.html#directive-option-autoclass-class-doc-from).

I tried changing to "class-doc-from": "init" but that again did not render the __init__ docstring.
