Actually I was referring to the reference that user agents can choose to include all elements with tabindex="-1" in the tab order.

I think that would be a bad road to go down...

I take it that in the case I outlined, that aria-hidden is being used poorly?  Or perhaps the combination of aria-hidden/tabindex="-1".  "On the assumption the user can see it ..." and it is actually functional, then marking aria-hidden AND tabindex="-1" is a bad idea.

BTW, all I was doing was using the use case from the HTML spec I cited earlier, where it says ignoring negative tabindex is okay in certain cases.  I didn't see how adding aria-hidden changed that use case.
