1893707 - ARIA: remove aria-expanded from supported attributes from role listbox

Status: RESOLVED FIXED

(Core :: Disability Access APIs, enhancement, P5)

Description

[spectranaut]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/115.0

Expected results:

ARIA is removing aria-expanded from listbox role's supported attribute list: https://github.com/w3c/aria/pull/1862

Rule 5 in CORE-AAM's State and Property Mapping General Rules (https://w3c.github.io/core-aam/#statePropertyMappingGeneralRules) says:

Some WAI-ARIA properties are not global, and are only supported on certain roles. If a non-global WAI-ARIA state or property is used where it is not supported, user agents SHOULD NOT map the given WAI-ARIA property to the platform accessibility API. For example, if aria-checked="true" is specified on <div role="grid">, it should not be exposed in MSAA implementations as STATE_SYSTEM_CHECKED.

Valerie mentioned these are likely good first bugs, so I'm marking them as such. Please feel free to correct if that's not accurate.
