[orca-list] thunderbird and orca master

[jérémy prego <jeremy pregonetwork net>]

hello Joanie,
thunderbird 52.6.0, orca master.

since the different commits of today, orca does not stop to say 
"editable content" on each line in the drafting of an e-mail with 
Thunderbird

step to reproduce:
1. open a new message
2. go in the body of the message
3. write skipping lines
4. orca says "editable content"

thanks

jerem.

P.S. sorry for my english.
