--- Comment #31 from Ferdinand Prantl <prantlf at gmail.com> ---
May I asked about the state of this issue, please?

Safari is the only browser, which doesn't include the state "mixed" in the accessibility tree, when the property `indeterminate` is set to true on an input element of the type "checkbox". Both Chrome and Firefox do it and a screen reader can read the checkbox state properly. Safari doesn't and it causes more work for application developers, who have to support Safari by a custom checkbox element.

Can WebKit work the same like other browsers, which use two boolean properties to control the state in the accessibility tree?

    indeterminate = true  =>  "mixed"
    otherwise             =>  checked ? "checked" : "unchecked"
