[orca-list] Sometime if a letter containing a link, after scrolling down a line cursor jumps the first line of the letter

[Hammer Attila <hammera pickup hu>]

Hy,

I experienced an issue with Thunderbird 12.0 and all Orca versions:
If a letter containing a link, caret navigation works right until the 
caret not land the link. After this when I press a Down arrow key, the 
caret moving the top of line the message. When I try moving again after 
the link with arrow keys, the problem beginning again. This problem 
happening usual with unread messages.

Not always happening this situation, and after I doed an orca --replace 
command, I possible reading entire letter.
Unfortunately I unable to make a debug.out yet when I experiencing this 
issue, because when run orca --replace --debug-file=debug.out command 
and opening again the letter, the issue is not happened me. :-(:-(

I use following possible this problem related app settings in Orca with 
Thunderbird related:
Grab focus on objects when navigating check box: checked,
Sayall webpage when first load check box: checked.

Anybody experienced this type issue?
This is an Orca or Thunderbird bug?
Unfortunately I wery often get's commit notifications or bugreport 
notifications with some time important reading the entire content.
