Getting duplicate object definitions for class attributes when having both docstring and type hints.

[ahan2911]

Describe the bug

When using both sphinx_autodoc and sphinx_autodoc_typehints extensions. And in class having attribute definition in docstring as well as type hint for the same. Then getting duplicate object definitions.
Is there any way to prefer docstring over type hint for definition of object. I want both extensions to be enabled.

Can you please edit the post to fix the source fences?

using both sphinx_autodoc and sphinx_autodoc_typehints extensions

Since this is an issue specific to the sphinx_autodoc_typehints extension I think you should ask at their repository. This is bound to be a common usage question so also consider searching the Sphinx tag at Stack Overflow. Please see the Get Help because this issue tracker is mostly for bugs and feature requests, not for usage questions.

This seems potentially similar to an issue already reported in sphinx-autodoc-typehints at tox-dev/sphinx-autodoc-typehints#419 - please feel free to correct me if I'm mistaken.
