We have implementations done in Chrome and almost done in Firefox. We as a
minimum require drawSystemFocusRing. Both IBM and Pearson need to this
function and we cannot afford to exclude low vision users in this release.

Look guys, I appreciate that catching up is not a lot of fun (such as the
IE UAIG mappings:
) but other people have done the work. It is inappropriate to hold up this
work just because you are behind.

Based on the feedback from Jatinder and Apple, Microsoft does not support
this proposal.  We believe that the focus ring APIs need significant work,
and should be moved to L2 rather than put at risk in L1.

I believe the CfC is concerned with testing for consensus about which a11y
items are expected in the current Canvas revision, i.e. "At Risk"
for the moment but implemented and testable in the near term, versus those
we agree to postpone to "level 2," if I'm recalling the nomenclature

This is different, imo, from a discussion of optimal naming of the methods.
Can we not conclude testing consensus over this even as we continue to
discuss optimal naming of these methods?
