smaug, which browser is correct? If we are correct per spec, does it make sense for the spec to say whatever it says?

I think even if the behaviour of Firefox is conformant to the spec, it doesn't make sense to disallow a focusable element to be tabbed to while allowing it to be focused by click.

It make senses to totally disallow focus by either tab or click, or to totally allow it.

I would expect us to have still issues here.

So if host itself is focusable, it should be focused just like any other normal element. Then later we'll enter its scope.
