[orca-list] Orca skips certain potentially non-navigable ads (was Re: Orca skips content on a web page)

[Joanmarie Diggs <jdiggs igalia com>]

Aha. It's not a Gecko bug -- it's a workaround for a different Gecko 
bug. In particular, certain ads served up from doubleclick.net had -- 
and potentially still have -- weird accessibility problems that caused 
users to get stuck or loop in their ads. If memory serves me, this was 
especially true if the ads regularly changed or updated in the page.

The links in question are from an ad served up by doubleclick.net. 
So.... What would you like me to do: Remove that filter and cause you to 
potentially be able to access these links via line navigation, but at 
the risk of getting permanently stuck in other ads? Or should I leave 
things as-is?

Instead of saying "blank", I could potentially say something to alert 
the user to the fact that there's an ad here, but we're in string freeze 
now.

BTW: The reason you can access these links with the latest Chromium 
built from source is that Chromium is exposing these ads differently and 
my filter isn't catching them (yet). That said, I'm tempted to leave the 
filter as-is for now, until we determine if other ads prove problematic 
for Chromium. Unlike Gecko, Chromium doesn't have the huge amount of 
accessible-text bugs, thus getting stuck in Chromium is far less likely.
