Summary: HTML anchor elements have ping, rel, referrerPolicy, relList,

Bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1451823
I looked at the patch briefly, and I'm a bit confused about the state of
<a ping> . Specifically, my understanding is that we don't currently
ship it - it's behind a pref and it's off by default (
https://searchfox.org/mozilla-central/source/modules/libpref/init/all.js#303
). However, we have support in the codebase. But it looks to me like the
patch on the bug doesn't really check this pref (unsure if we expose
<a>.ping for HTML if the pref is off) and doesn't alter the
implementation. At a minimum, it looks to me like this check:
https://searchfox.org/mozilla-central/source/docshell/base/nsPingListener.cpp#255-259
would need updating to actually support <a>.ping "properly" for SVG.
