[5c01ea] ARIA state or property is permitted - Passed Example 6-7-8-10-12 improvement

[shunguoy]

In ARIA state or property is permitted, Passed Examples 6, 7, 8 and 10
do not fully adhere to the ARIA specifications for required and supported states and properties.

1. The only required state and property for the combobox role is area-expanded, the aria-controls is no longer required. This applies to the examples 6, 7, and 8. The descriptions and the code for those examples need to be updated.

2. The role='none' is invalid for a button element per ARIA in HTML. Thus, the description and code for the example need to be updated.
   ACT rules are cool!

3. remove aria-hidden="true" from example 12 because of the explicit style="display: none;".
   On

I'm fine (agree) with it.

I don't believe we need to make any changes, as the applicability clearly states, "This rule checks that WAI-ARIA states or properties are allowed for the element they are specified on." We're not checking the roles. So, even though you're assigning role="none" to a focusable button, which isn't allowed, it triggers the presentational roles conflict resolution, resulting in a computed role of "button" with an aria-pressed attribute. The example works fine for me as it is.

remove aria-hidden="true" from example 12 because of the explicit style="display: none;".

I think we can leave it as is. From a programmatic perspective, authors might want to always remove the content programmatically using aria-hidden="true", considering that aria-checked is used to convey that information. However, through js, the author might also want to visually hide something. I don't see why this should be an issue (while there is some redundancy, I understand why authors may choose to do this, as it requires extra effort on their side to also remove/add the aria-hidden attribute every time).

Discussed in the CG group and agreed to only fix the first item in the list.
