CFC: transition Aria in HTML to CR

[LJWatson]

This is a Call For Consensus (CFC) to transition ARIA in HTML to Candidate Recommendation (CR).

The results of the most recent horizontal review were tracked in #273, and there are no outstanding issues.

An implementation report is also available. All but 14 features have at least two implementations, and those 14 are noted as being "at risk" should the implementations not happen before we exit CR.

If you support this proposal, please add a "thumbs up" reaction to this comment.

If you do not support the proposal, please add a "thumbs down" reaction to this comment instead, and post a comment with your reasons.

If you do not respond to this CFC at all, W3C convention regards it as implicit support for the proposal. It is therefore much better if you respond directly.

Please respond to this CFC by the end of your day on Friday 25 July 2021. Thank you.

note: additional HTML Validator updates have reduced the at risk features list by two items

Given that now all engines handle case insensitive matching, I'd still like to see issue #280 addressed and #287 merged.
