#934 8acefc3 Thanks @alonidiom! - Support aria-description as descriptor

#933 a593ee0 Thanks @jlp-craigmorten! - Support "none" role as a synonym for the "presentation" role

#893 d5af41d Thanks @eps1lon! - Don't consider title in 2E

Effectively ensures that title will not have precedence over name from content. For example, the option in <option title="Title">Content</option> will now have "Content" as its accessible name instead of "Title".

#811 5b0f48e Thanks @eps1lon! - Prefer button subtree over title attribute.

 const name = computeAccessibleName(<button title="from-title">from-content</button>);
-'from-title' === name
+'from-content' === name

<button title="from-title">from-content</button> would previously compute the accessible name "from-title". This is correct in ACCNAME 1.2 but is changed in the latest editors draft. The latest editors draft specifically refers to HTML-AAM which says that the subtree should take precedent over the title attribute. computeAccessibleName now calculates "from-content" as the accessible name.
