I see the indentation changed, and it looks more disorganized in later one

Sphinx 2.0 recently came out. I noticed quite a few backwards incompatibilities in the changelog, maybe this is related.

As far as I had tried with the maintained numpydoc extension, the problem still remains, and it is a dead end.
I haven't tried with napoleon yet.

Okay, I've also tried with napoleon but things are not working too.

It may possibly be broken from the sphinx side (e.g. issue sphinx-doc/sphinx#6262)
I see the parameters sections are technically rendered as field lists, and it seems like we to change the style to something other than classic, or patch our CSS theme to get it working

I've applied the one sphinx-doc/sphinx#6266 manually, and things may not be identical as previous, but seems like working.
