[4e8ab6] Element with role attribute has required states and properties - Combobox Failed Example 6

[giacomo-petri]

In rule Element with role attribute has required states and properties, combobox Failed Example 6 requires the aria-controls attribute.

In ARIA 1.2 specs the aria-controls attribute is required, but since aria-controls has no support at all, it has been removed in ARIA 1.3.

Although this technically violates ARIA 1.2 (until version 1.3 is officially released), requiring support for a property that no UA/AT currently supports seems like overkill for the author to me.

I suggest switching aria-expanded and aria-controls so that the example remains meaningful, aligns with ARIA 1.3 when it's released, and requires no further changes.

I just realised that Failed Example 5 is covering the missing aria-expanded scenario, so the suggestion doesn't work and probably we should simply remove the example.
