[orca-list] Concerns about handling of aria-atomic

[Nolan Darilek <nolan thewordnerd info>]

I keep encountering situations where Orca doesn't seem to handle 
aria-atomic="true" like I'd expect. It often doesn't speak the first 
value in a div, for instance. I know recently I reported something 
similar, but I hit another issue like it and started to wonder. I found 
this test:

Look at Game 2. According to the description, screen readers should read 
the entire scoreboard whenever a value changes. Orca only seems to read 
the element with a change, though. That is, it only reads the team with 
a changed score, not the entire scoreboard div with both teams. I don't 
know if this is an accurate description of what should happen, or indeed 
if it is why my ARIA live regions are misbehaving. But it does seem to 
be a deviation, so I thought I'd bring it up.


Thanks!
