[orca-list] Content crossing window boundaries

[Nolan Darilek <nolan thewordnerd info>]

Hit this one yesterday and it disoriented the hell out of me. :) To 
reproduce:

1. From an existing Firefox window, open an entirely new window.
2. Visit etherpad.org, click the "Try a demo" button.
3. Make sure focus lands in the pad. This doesn't happen automatically, 
I have to do a bit of tabbing and alt-f9, maybe due to the iframe focus 
bug from last week.
4. Once you're sure arrowing around reports the pad contents, switch 
back to the first window with alt-`.
5. Arrow around.

Doing this, I seem to still get the pad contents. If I tab, I get links 
from the first window. Not sure whose issue this is, but it happens with 
Orca master from Friday and Firefox stable (whatever Fedora 23 ships 
with all updates applied.)

As a related aside, would it be possible to speak Etherpad's formatting 
details when editing? This does seem to happen in browse mode, but not 
in focus mode. So for instance if I arrow into an Etherpad heading, I 
hear "Heading" in browse mode but not focus mode. NVDA does call it a 
"heading level 1" so maybe there's some additional information being 
exposed by Etherpad's a11y support that Orca isn't getting? Making it 
work in focus mode would be great for WYSIWYG editing. Anyhow, I know a 
new release is imminent so this isn't high-priority, but I've been using 
Etherpad lots lately and this would be a nice-to-have if it's not too 
painful. :) Drafting some docs I want collaborative feedback on over the 
next few weeks, and for the moment I'm doing the bulk of my editing in 
my Windows VM.

Thanks.
