Bug report

I've just build the matplotlib docs with sphinx master (future 2.0) and some of the styling has gone bad:

Edit: Let's collect all the doc rendering problems in this issue, so that we know what we have to fix later on:

List of issues:

• Numpydoc parameters section title rendered incorrectly (see below in this comment, @dstansby: fixed in sphinx 2.1.2)
• No space between parameter names and types in numpydoc parameters sections (see below in this comment, upstream bug: Sphinx 2.0 compatibility issue? numpy/numpydoc#215, , fix in Fix API contents display for sphinx 2 #14105).
• Some headlines broken (Style issues when building the docs with (future) Sphinx 2.0 #13591 (comment), fixed in sphinx 2.1)
• Wrapping after bullet points in table of contents (Style issues when building the docs with (future) Sphinx 2.0 #13591 (comment), fix in Fix API contents display for sphinx 2 #14105)
• Table rendering (Style issues when building the docs with (future) Sphinx 2.0 #13591 (comment))
• Rendering of list of methods (Style issues when building the docs with (future) Sphinx 2.0 #13591 (comment))
• Search is broken (Style issues when building the docs with (future) Sphinx 2.0 #13591 (comment), fixed in sphinx 2.0.1)

Issue: Numpydoc parameters section

[ ] Need to check if there will style changes in sphinx 2.0 and possibly adapt mpl.css.
