Right...

yeah.

Yes, I hope not :)

So it seems that a real question is whether browsers prefer to deal with  
two APIs, or allow customisation of "the" focus ring. which comes down to  
a question of implementation strategy - do browsers rely on a system focus  
style, or draw it themselves, feeding from a system default style?
