[orca-list] Mouse review: On the Firefox profile dialog Orca repeats the title on each element

[Alex ARNAUD <alexarnaud hypra fr>]

Hello all,

Environment:
- Debian Stretch with latest a11y stack, it's my own personal computer 
to check mouse review on more scenario
- Orca master
- Firefox ESR 52 (without e10s)

Steps to reproduce:
1) Launch Firefox profile dialog with the command "Firefox -P"
2) Move over different elements with the mouse

Result: Orca announces the window title on each items
Expected result: Orca should announce the title only one time

Best regards.
