*Summary*: Currently, custom elements lack the ability to set default accessibility semantics that built-in elements have. This feature allows for the setting of defaults through the custom element's ElementInternals via ARIA reflection, without affecting elements that have accessibility attributes set on them directly.
*Bug*: Bug 1665151 <https://bugzilla.mozilla.org/show_bug.cgi?id=1665151> *Specification*: https://github.com/whatwg/html/pull/4658 *Standards Body*: WHATWG *Standards position: * https://github.com/mozilla/standards-positions/issues/201 *Platform coverage*: All *Preference*: This feature relies on Aria Reflection <https://bugzilla.mozilla.org/show_bug.cgi?id=1628418> and so is currently gated behind the accessibility.ARIAReflection.enabled pref. *DevTools bug*: n/a *Other browsers*: - Blink: Shipping by default as of version 81 ( https://chromestatus.com/feature/5962105603751936) - WebKit: Has open implementation bug ( https://bugs.webkit.org/show_bug.cgi?id=216570) *web-platform-tests*: A surface-level-only test was provided at https://github.com/web-platform-tests/wpt/pull/18223. Deeper tests do not appear possible with WPT currently: https://github.com/web-platform-tests/wpt/issues/7753, so Gecko-specific tests are being written as well. -- You received this message because you are subscribed to the Google Groups "[email protected]" group.
