If we don't have a 2nd implementation, I rather we leave Hit Regions specified in the Level 2 spec and not delay the Level 1 spec by bringing it back. The Level 1 spec will already have drawFocusIfNeeded() with two implementations and we have agreed in the past that this API will provide the minimum level of accessibility support that needs to be in the Level 1 spec. Of course, we should continue working on Hit Region implementations and coordinate feedback, I just don't think that discussion is precluded on bringing it to the Level 1 spec.

We do not.
They are listed as at-risk so we can still go to CR with them.

We should probably update the at-risk list to state that part or all of hit regions might be removed.

I just requested that the patches are checked into firefox.
If all goes well, this means that the upcoming nightly build will have basic support for hit regions.

If people had earlier tests for drawFocusIfNeeded, they can simply update them as follows.
old code:
ctx.drawFocusIfNeeded(element);
new code:
ctx.drawFocusIfNeeded(element);
ctx.addHitRegion({control: element};

Alex, how can we turns hit regions and focus rings on by default?

Hi. Here's an update of hit region implementation in Firefox in case if you're curious .
This week we've got a prototype of hit regions which can be used to change accessible boundaries. The work hasn't been landed into Firefox Nightly yet but there's a try build [2].
There's no plans to continue the work on drawFocusIfNeeded to fit it for accessible boundaries setting since hit regions looks promising. It's worth to notice though that drawFocusIfNeeded (used to draw the focus) is part of Firefox and there's no actions to undo this.

You can follow hit regions work by watching Mozilla bug [1].
Thanks.
Alexander.
