Bug ID: 273333
Summary: AX: ARIA: remove aria-expanded from supported
attributes from role listbox
Product: WebKit
Version: WebKit Nightly Build
Hardware: All
OS: All
Status: NEW
Severity: Normal
Priority: P2
Component: Accessibility
Assignee: webkit-unassigned at lists.webkit.org

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.
