Add support for ARIA 1.1 attribute 'none' http://www.w3.org/TR/wai-aria-1.1/#none An element whose implicit native role semantics will not be mapped to the accessibility API.

Yeah, the "none" role is just a synonym of "presentation" role. (FWIW, neither is an attribute. Removing "@none" from the title.)
