           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: P2

accessible-event listener

Steps to reproduce:
1. Launch the attached accessible-event listener in a terminal
2. Load the attached test case is MiniBrowser
3. Tab into the combo box with the keyboard (focus on it)
4. Navigate the different options with the keyboard (using arrow keys)

Expected results:

In the terminal, you should see that the selection-changed signal is being emitted from WebCore, by printing lines like the following one:

  Selection changed for 'combo box' object. RAW DATA:
   object:selection-changed(0, 0, 0)
    source: [combo box | bar]
    host_application: [application | WebKitWebProcess]

Actual results: Nothing is printed by the listener app, meaning that no signal is being emmitted.

Note: This works fine in epiphany 3.10.3, so it's a bug in master.
