           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: Linux

pyatspi accessible-event listener

Steps to reproduce:
1. Launch a Gtk3 minibrowser
2. Launch the attached accessible-event listener in a terminal
3. Tab from the URL/location bar down into the content
4. Tab within the content (www.webkitgtk.org)
5. Follow a link from the content (e.g. epiphany)
6. Tab within the newly-loaded content

Expected results: Focused-changed events would always be fired and would come from a valid host application

Actual results:

* On step 3, focus events are emitted as expected:
  object:state-changed:focused(1, 0, 0)
        source: [text | ]
        host_application: [application | MiniBrowser]
        sender: [application | MiniBrowser]
  object:state-changed:focused(1, 0, 0)
        source: [push button | Refresh]
        host_application: [application | MiniBrowser]
        sender: [application | MiniBrowser]
  object:state-changed:focused(1, 0, 0)
        source: [push button | Find]
        host_application: [application | MiniBrowser]
        sender: [application | MiniBrowser]
 object:state-changed:focused(1, 0, 0)
        source: [toggle button | Menu]
        host_application: [application | MiniBrowser]
        sender: [application | MiniBrowser]

* On step 4, no focus events are emitted at all

* On step 6, the focus events are emitted, but from a "dead" host application:

  object:state-changed:focused(1, 0, 0)
        source: [link | Apps]
        host_application: [DEAD]
        sender: [DEAD]
  object:state-changed:focused(1, 0, 0)
        source: [link | Web]
        host_application: [DEAD]
        sender: [DEAD]
  object:state-changed:focused(1, 0, 0)
        source: [link | Home]
        host_application: [DEAD]
        sender: [DEAD]
  object:state-changed:focused(1, 0, 0)
        source: [link | RecentChanges]
        host_application: [DEAD]
        sender: [DEAD]

Impact: Orca does not present the focus changes emitted from the document content.
