Invisible content focusable ?

[cescarment]

Hello,
In the example (http://a11y.nicolas-hoffmann.net/tabs/), you use an invisible title H2, with a tabindex in order to make this element focusable.
Is it correct for WCAG ? I don't think so, the focus isn't visible :

2.4.7 Focus Visible: Any keyboard operable user interface has a mode of operation where the keyboard focus indicator is visible. (Level AA)

Hello,

I've checked with a WCAG expert, he told me that it is correct, as the invisible h2 is only focusable (reach-able) but not operable.

Hope that this answers your question. :)
