[Jonathan Watt [:jwatt]]

Spec issue #13067 was discussed at TPAC and the resolution is to add a new none value for position-anchor, make it the default, and use the UA style sheet for the previous auto stuff.

If I'm following the discussion/resolution correctly, I think this is fairly simple. Pushed https://treeherder.mozilla.org/jobs?repo=try&revision=38f2cb7117be96ac3696782fb982edb7ce2b0dc8 with a draft patch to see how it looks.
