It's not great, but given how often this page is updated, for the time
being I pushed the following workaround.
(The id="cxx2a" is now with the first paragraph, not the actual header.)
Still will be good to look into the script itself.

Subject: [PATCH] cxx-status: Work around issue in bin/preprocess-html.py
This script rewrites
<h2 id="cxx20"><a id="cxx2a">C++20 Support in GCC</a></h2>
to
<h2 id="cxx20"><a id="cxx2a"><a href="#cxx20"><a id="cxx2a">C++20...
which is not proper HTML and duplicates the <a id="cxx2a"> tag.
Work around this by pushing id="cxx2a" into the following <p>.
