Lacking Announcements for the Switch Role #948

We have two lacking announcements related to the “switch” role:

1. Aria-readonly=”true” for a “switch” doesn’t lead to the announcement of the read only state.
2. There is no keyboard hint (tutor message) for the “switch” e.g. “Press enter to activate”

Native HTML Example
-Aria-readonly=”true” for a “switch” doesn’t lead to the announcement of the read only state

-There is no keyboard hint (tutor message) for the “switch” e.g. “Press enter to activate”
(native HTML sample: https://www.w3.org/WAI/ARIA/apg/patterns/switch/examples/switch/)

Aria-readonly attribute is supported for a “switch” according to wai-aria 1.2: https://www.w3.org/TR/wai-aria-1.2/#switch

Both bugs we've indicated as they're related to the "switch" role.”
