#16175: [GTK] Accessible application reports ATK_STATE_DEFUNCT after combo box is
collapsed
----------------------+---------------------------
 Reporter:  jdiggs@…  |      Owner:
     Type:  defect    |     Status:  new
Milestone:            |  Component:  pidgin (gtk)
  Version:  2.10.9    |   Keywords:  accessibility
----------------------+---------------------------
 Steps to reproduce:
 1. Launch the attached accessible-event listener in a terminal
 2. Launch pidgin and get into the Add Account dialog
 3. Give focus to the protocol combo box and press space to expand it
 4. Press Escape to collapse the combo box

 Expected results: The accessible associated with the pidgin application
 would not claim to be defunct.

 Actual results: The accessible associated with the pidgin application
 claims to be defunct.

 Sample output performing the steps above:

 {{{
 [combo box | Proxy type:] [application | Pidgin] [application | Pidgin]
 [combo box | AIM] [application | Pidgin] [application | Pidgin]
 [menu item | AIM] [application | Pidgin] [application | Pidgin]
 [menu | ] [application | Pidgin] [application | Pidgin]
 [combo box | AIM] [application | Pidgin] [application | Pidgin]
 [menu item | AIM] [application | Pidgin] [application | Pidgin]
 [menu | ] [application | Pidgin] [application | Pidgin]
 [combo box | AIM] [DEAD] [DEAD]
 [combo box | AIM] [DEAD] [DEAD]
 }}}


 Note: This doesn't happen with gtk-demo for Gtk+ 2 or Gtk+ 3, so I believe
 it's specific to Pidgin's interface.

 I'm using Pidgin 2.10.9-1.fc21 (libpurple 2.10.9).
