[orca-list] Firefox : command "Go to end of container" goes to the end of the wrong list on a page

[Alex ARNAUD <alexarnaud hypra fr>]

Dear Orca maintainers,

Environment :
- Debian 8.7
- Orca master
- Firefox ESR 45.7.0

Steps to reproduce :
1) Open the following page in Firefox : 
https://fosdem.org/2017/schedule/event/osd_accessibility_in_os/
2) Go the the fourth list begins by " Track: Open Source Design devroom"
3) Press comma to skip to the end of the container

Result : Orca goes to the end of the container but jumps on the first 
item of the previous list (the link labeled "FOSDEM 2017")

Expected result : Orca should go to the next paragraph begins by "There 
are many".


Best regards.
