           Summary: [Gtk] Implement STATE_FOCUSED, STATE_FOCUSABLE, and
                    corresponding events for text objects
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Accessibility
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: joanmarie.diggs at gmail.com

According to: http://library.gnome.org/devel/atk/stable/atk-AtkState.html:

~~~
ATK_STATE_FOCUSABLE
    Indicates this object can accept keyboard focus, which means all events
resulting from typing on the keyboard will normally be passed to it when it has
focus

ATK_STATE_FOCUSED
    Indicates this object currently has the keyboard focus 
~~~

While I typically think of "focusable" being akin to "I can Tab to it," it
seems to be used to mean "the active object." Thus we expect objects which
implement the accessible text interface to have STATE_FOCUSABLE if the user can
interact with the object via keyboard and STATE_FOCUSED if the user is
interacting with the object. The corresponding events (focus: and
object:state-changed:focused) are also expected.

WebKit objects of ROLE_TEXT lack these states and events.

While I can work around the absence of these things in some cases, there are
other cases in which one needs to know if an object has focus. Example:
distinguishing caret navigation related object:text-caret-moved and
object:text-selection-changed events from the same events seen when using
Epiphany's Find toolbar.
