[orca-list] Problems using the object list

[José Vilmar Estácio de Souza <vilmar informal com br>]

Hi all.

To reproduce try the following steps:

1. Launch firefox, press ctrl+k and type 'linux 4.3 news', without the 
quotations.

2. Press the enter key and wait for the page to load.

--
3. Press alt+shift+k to activate the list of links.

4. Type linux and press tab.

Expected results:
After I press tab, a link with the word linux should be focused in the list.

Actual results:
Seems that the focus do not change in the list and orca does not announce the current link.

Happens with orca from master and orca 3.18.1.
Am I doing something wrong?
Thanks.
