E.g. on:

https://github.com/scikit-learn/scikit-learn/blob/main/README.rst

You get something that looks like:

Notice in particular the first badge for our Azure Pipelines CI that is missing and the trailing underscores that show up everywhere.

However the same README.rst contents render well on pypi.org (assuming it has not changed since the last release):

https://pypi.org/project/scikit-learn/

I think it used to be rendered correctly on github a couple of days/weeks ago. Looking at the source of README.rst I cannot spot the source of the problem. Has anybody an idea?
