[orca-list] Icedove : read by word partially broken in some contexts

[Alex ARNAUD <alexarnaud hypra fr>]

Dear Orca maintainer and all,

I've noticed that the read by word feature of Orca is partially broken 
in Icedove (maybe Thunderbird also) in some contexts.

Environment :
- Debian 8.7
- Icedove 45.6.0
- Orca master (commit e13a67ef6f2c117e40b595e9338e0bcedaf00a4d)

Steps to reproduce :
1) Open Icedove
2) Write a new mail in HTML mode
3) Add a line with two word ended by a space
4) Go to the beginning of the line with origin
5) Go to the end of the line with ctrl+right
6) Go to the last word before the space with ctrl+left

Result : Orca announces the whole line
Expected result : Orca should announce the current word

Best regards.
